			<![CDATA[Provides access to configuration parameters.

			<h4 id="Resources">Resources</h4>

			<p>Configurations are specified by resources. A resource contains a set of
			name/value pairs as XML data. Each resource is named by either a
			<code>String</code> or by a {@link Path}. If named by a <code>String</code>,
			then the classpath is examined for a file with that name. If named by a
			<code>Path</code>, then the local filesystem is examined directly, without
			referring to the classpath.

			<p>Unless explicitly turned off, Hadoop by default specifies two
			resources, loaded in-order from the classpath: <ol>
			<li><tt><a href="{@docRoot}/../core-default.html">core-default.xml</a>
			</tt>: Read-only defaults for hadoop.</li>
			<li><tt>core-site.xml</tt>: Site-specific configuration for a given hadoop
			installation.</li>
			</ol>
			Applications may add additional resources, which are loaded
			subsequent to these resources in the order they are added.

			<h4 id="FinalParams">Final Parameters</h4>

			<p>Configuration parameters may be declared <i>final</i>.
			Once a resource declares a value final, no subsequently-loaded
			resource can alter that value.
			For example, one might define a final parameter with:
			<tt><pre>
			<property>
			<name>dfs.client.buffer.dir</name>
			<value>/tmp/hadoop/dfs/client</value>
			<b><final>true</final></b>
			</property></pre></tt>

			Administrators typically define parameters as final in
			<tt>core-site.xml</tt> for values that user applications may not alter.

			<h4 id="VariableExpansion">Variable Expansion</h4>

			<p>Value strings are first processed for <i>variable expansion</i>. The
			available properties are:<ol>
			<li>Other properties defined in this Configuration; and, if a name is
			undefined here,</li>
			<li>Properties in {@link System#getProperties()}.</li>
			</ol>

			<p>For example, if a configuration resource contains the following property
			definitions:
			<tt><pre>
			<property>
			<name>basedir</name>
			<value>/user/${<i>user.name</i>}</value>
			</property>

			<property>
			<name>tempdir</name>
			<value>${<i>basedir</i>}/tmp</value>
			</property></pre></tt>

			When <tt>conf.get("tempdir")</tt> is called, then <tt>${<i>basedir</i>}</tt>
			will be resolved to another property in this Configuration, while
			<tt>${<i>user.name</i>}</tt> would then ordinarily be resolved to the value
			of the System property with that name.]]>

			<![CDATA[Creates a symbolic link to an existing file. An exception is thrown if
			the symlink exits, the user does not have permission to create symlink,
			or the underlying file system does not support symlinks.

			Symlink permissions are ignored, access to a symlink is determined by
			the permissions of the symlink target.

			Symlinks in paths leading up to the final path component are resolved
			transparently. If the final path component refers to a symlink some
			functions operate on the symlink itself, these are:
			- delete(f) and deleteOnExit(f) - Deletes the symlink.
			- rename(src, dst) - If src refers to a symlink, the symlink is
			renamed. If dst refers to a symlink, the symlink is over-written.
			- getLinkTarget(f) - Returns the target of the symlink.
			- getFileLinkStatus(f) - Returns a FileStatus object describing
			the symlink.
			Some functions, create() and mkdir(), expect the final path component
			does not exist. If they are given a path that refers to a symlink that
			does exist they behave as if the path referred to an existing file or
			directory. All other functions fully resolve, ie follow, the symlink.
			These are: open, setReplication, setOwner, setTimes, setWorkingDirectory,
			setPermission, getFileChecksum, setVerifyChecksum, getFileBlockLocations,
			getFsStatus, getFileStatus, exists, and listStatus.

			Symlink targets are stored as given to createSymlink, assuming the
			underlying file system is capable of storign a fully qualified URI.
			Dangling symlinks are permitted. FileContext supports four types of
			symlink targets, and resolves them as follows
			<pre>
			Given a path referring to a symlink of form:

			<---X--->
			fs://host/A/B/link
			<-----Y----->

			In this path X is the scheme and authority that identify the file system,
			and Y is the path leading up to the final path component "link". If Y is
			a symlink itself then let Y' be the target of Y and X' be the scheme and
			authority of Y'. Symlink targets may:

			1. Fully qualified URIs

			fs://hostX/A/B/file Resolved according to the target file system.

			2. Partially qualified URIs (eg scheme but no host)

			fs:///A/B/file Resolved according to the target file sytem. Eg resolving
			a symlink to hdfs:///A results in an exception because
			HDFS URIs must be fully qualified, while a symlink to
			file:///A will not since Hadoop's local file systems
			require partially qualified URIs.

			3. Relative paths

			path Resolves to [Y'][path]. Eg if Y resolves to hdfs://host/A and path
			is "../B/file" then [Y'][path] is hdfs://host/B/file

			4. Absolute paths

			path Resolves to [X'][path]. Eg if Y resolves hdfs://host/A/B and path
			is "/file" then [X][path] is hdfs://host/file

			<![CDATA[The FileContext class provides an interface to the application writer for
			using the Hadoop file system.
			It provides a set of methods for the usual operation: create, open,
			list, etc

			<p>
			<b> * Path Names * </b>
			<p>

			The Hadoop file system supports a URI name space and URI names.
			It offers a forest of file systems that can be referenced using fully
			qualified URIs.
			Two common Hadoop file systems implementations are
			<ul>
			<li> the local file system: file:///path
			<li> the hdfs file system hdfs://nnAddress:nnPort/path
			</ul>

			While URI names are very flexible, it requires knowing the name or address
			of the server. For convenience one often wants to access the default system
			in one's environment without knowing its name/address. This has an
			additional benefit that it allows one to change one's default fs
			(e.g. admin moves application from cluster1 to cluster2).
			<p>

			To facilitate this, Hadoop supports a notion of a default file system.
			The user can set his default file system, although this is
			typically set up for you in your environment via your default config.
			A default file system implies a default scheme and authority; slash-relative
			names (such as /for/bar) are resolved relative to that default FS.
			Similarly a user can also have working-directory-relative names (i.e. names
			not starting with a slash). While the working directory is generally in the
			same default FS, the wd can be in a different FS.
			<p>
			Hence Hadoop path names can be one of:
			<ul>
			<li> fully qualified URI: scheme://authority/path
			<li> slash relative names: /path relative to the default file system
			<li> wd-relative names: path relative to the working dir
			</ul>
			Relative paths with scheme (scheme:foo/bar) are illegal.

			<p>
			<b>**The Role of the FileContext and configuration defaults**</b>
			<p>
			The FileContext provides file namespace context for resolving file names;
			it also contains the umask for permissions, In that sense it is like the
			per-process file-related state in Unix system.
			These two properties
			<ul>
			<li> default file system i.e your slash)
			<li> umask
			</ul>
			in general, are obtained from the default configuration file
			in your environment, (@see {@link Configuration}).

			No other configuration parameters are obtained from the default config as
			far as the file context layer is concerned. All file system instances
			(i.e. deployments of file systems) have default properties; we call these
			server side (SS) defaults. Operation like create allow one to select many
			properties: either pass them in as explicit parameters or use
			the SS properties.
			<p>
			The file system related SS defaults are
			<ul>
			<li> the home directory (default is "/user/userName")
			<li> the initial wd (only for local fs)
			<li> replication factor
			<li> block size
			<li> buffer size
			<li> bytesPerChecksum (if used).
			</ul>

			<p>
			<b> * Usage Model for the FileContext class * </b>
			<p>
			Example 1: use the default config read from the $HADOOP_CONFIG/core.xml.
			Unspecified values come from core-defaults.xml in the release jar.
			<ul>
			<li> myFContext = FileContext.getFileContext(); // uses the default config
			// which has your default FS
			<li> myFContext.create(path, ...);
			<li> myFContext.setWorkingDir(path)
			<li> myFContext.open (path, ...);
			</ul>
			Example 2: Get a FileContext with a specific URI as the default FS
			<ul>
			<li> myFContext = FileContext.getFileContext(URI)
			<li> myFContext.create(path, ...);
			...
			</ul>
			Example 3: FileContext with local file system as the default
			<ul>
			<li> myFContext = FileContext.getLocalFSFileContext()
			<li> myFContext.create(path, ...);
			<li> ...
			</ul>
			Example 4: Use a specific config, ignoring $HADOOP_CONFIG
			Generally you should not need use a config unless you are doing
			<ul>
			<li> configX = someConfigSomeOnePassedToYou.
			<li> myFContext = getFileContext(configX); // configX is not changed,
			// is passed down
			<li> myFContext.create(path, ...);
			<li>...
			</ul>]]>

			<![CDATA[<h1>A client for the Kosmos filesystem (KFS)</h1>

			<h3>Introduction</h3>

			This pages describes how to use Kosmos Filesystem
			(<a href="http://kosmosfs.sourceforge.net"> KFS </a>) as a backing
			store with Hadoop. This page assumes that you have downloaded the
			KFS software and installed necessary binaries as outlined in the KFS
			documentation.

			<h3>Steps</h3>

			<ul>
			<li>In the Hadoop conf directory edit core-site.xml,
			add the following:
			<pre>
			<property>
			<name>fs.kfs.impl</name>
			<value>org.apache.hadoop.fs.kfs.KosmosFileSystem</value>
			<description>The FileSystem for kfs: uris.</description>
			</property>
			</pre>

			<li>In the Hadoop conf directory edit core-site.xml,
			adding the following (with appropriate values for
			<server> and <port>):
			<pre>
			<property>
			<name>fs.default.name</name>
			<value>kfs://<server:port></value>
			</property>

			<property>
			<name>fs.kfs.metaServerHost</name>
			<value><server></value>
			<description>The location of the KFS meta server.</description>
			</property>

			<property>
			<name>fs.kfs.metaServerPort</name>
			<value><port></value>
			<description>The location of the meta server's port.</description>
			</property>

			</pre>
			</li>

			<li>Copy KFS's <i> kfs-0.1.jar </i> to Hadoop's lib directory. This step
			enables Hadoop's to load the KFS specific modules. Note
			that, kfs-0.1.jar was built when you compiled KFS source
			code. This jar file contains code that calls KFS's client
			library code via JNI; the native code is in KFS's <i>
			libkfsClient.so </i> library.
			</li>

			<li> When the Hadoop map/reduce trackers start up, those
			processes (on local as well as remote nodes) will now need to load
			KFS's <i> libkfsClient.so </i> library. To simplify this process, it is advisable to
			store libkfsClient.so in an NFS accessible directory (similar to where
			Hadoop binaries/scripts are stored); then, modify Hadoop's
			conf/hadoop-env.sh adding the following line and providing suitable
			value for <path>:
			<pre>
			export LD_LIBRARY_PATH=<path>
			</pre>


			<li>Start only the map/reduce trackers
			<br />
			example: execute Hadoop's bin/start-mapred.sh</li>
			</ul>
			<br/>

			If the map/reduce job trackers start up, all file-I/O is done to KFS.]]>

			<![CDATA[<p>A distributed, block-based implementation of {@link
			org.apache.hadoop.fs.FileSystem} that uses <a href="http://aws.amazon.com/s3">Amazon S3</a>
			as a backing store.</p>

			<p>
			Files are stored in S3 as blocks (represented by
			{@link org.apache.hadoop.fs.s3.Block}), which have an ID and a length.
			Block metadata is stored in S3 as a small record (represented by
			{@link org.apache.hadoop.fs.s3.INode}) using the URL-encoded
			path string as a key. Inodes record the file type (regular file or directory) and the list of blocks.
			This design makes it easy to seek to any given position in a file by reading the inode data to compute
			which block to access, then using S3's support for
			<a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35.2">HTTP Range</a> headers
			to start streaming from the correct position.
			Renames are also efficient since only the inode is moved (by a DELETE followed by a PUT since
			S3 does not support renames).
			</p>
			<p>
			For a single file <i>/dir1/file1</i> which takes two blocks of storage, the file structure in S3
			would be something like this:
			</p>
			<pre>
			/
			/dir1
			/dir1/file1
			block-6415776850131549260
			block-3026438247347758425
			</pre>
			<p>
			Inodes start with a leading <code>/</code>, while blocks are prefixed with <code>block-</code>.

			A {@link FileSystem} for reading and writing files stored on
			<a href="http://aws.amazon.com/s3">Amazon S3</a>.
			Unlike {@link org.apache.hadoop.fs.s3.S3FileSystem} this implementation
			stores files on S3 in their
			native form so they can be read by other S3 tools.

			A note about directories. S3 of course has no "native" support for them.
			The idiom we choose then is: for any directory created by this class,
			we use an empty object "#{dirpath}_$folder$" as a marker.
			Further, to interoperate with other S3 tools, we also accept the following:
			- an object "#{dirpath}/' denoting a directory marker
			- if there exists any objects with the prefix "#{dirpath}/", then the
			directory is said to exist
			- if both a file with the name of a directory and a marker for that
			directory exists, then the file masks the directory, and the directory
			is never returned.

			<![CDATA[A wrapper for Writable instances.
			<p>
			When two sequence files, which have same Key type but different Value
			types, are mapped out to reduce, multiple Value types is not allowed.
			In this case, this class can help you wrap instances with different types.
			</p>

			<p>
			Compared with <code>ObjectWritable</code>, this class is much more effective,
			because <code>ObjectWritable</code> will append the class declaration as a String
			into the output file in every Key-Value pair.
			</p>

			<p>
			Generic Writable implements {@link Configurable} interface, so that it will be
			configured by the framework. The configuration is passed to the wrapped objects
			implementing {@link Configurable} interface <i>before deserialization</i>.
			</p>

			how to use it: <br>
			1. Write your own class, such as GenericObject, which extends GenericWritable.<br>
			2. Implements the abstract method <code>getTypes()</code>, defines
			the classes which will be wrapped in GenericObject in application.
			Attention: this classes defined in <code>getTypes()</code> method, must
			implement <code>Writable</code> interface.
			<br><br>

			The code looks like this:
			<blockquote><pre>
			public class GenericObject extends GenericWritable {

			private static Class[] CLASSES = {
			ClassType1.class,
			ClassType2.class,
			ClassType3.class,
			};

			protected Class[] getTypes() {
			return CLASSES;
			}

			}

			<![CDATA[<code>SequenceFile</code>s are flat files consisting of binary key/value
			pairs.

			<p><code>SequenceFile</code> provides {@link Writer}, {@link Reader} and
			{@link Sorter} classes for writing, reading and sorting respectively.</p>

			There are three <code>SequenceFile</code> <code>Writer</code>s based on the
			{@link CompressionType} used to compress key/value pairs:
			<ol>
			<li>
			<code>Writer</code> : Uncompressed records.
			</li>
			<li>
			<code>RecordCompressWriter</code> : Record-compressed files, only compress
			values.
			</li>
			<li>
			<code>BlockCompressWriter</code> : Block-compressed files, both keys &
			values are collected in 'blocks'
			separately and compressed. The size of
			the 'block' is configurable.
			</ol>

			<p>The actual compression algorithm used to compress key and/or values can be
			specified by using the appropriate {@link CompressionCodec}.</p>

			<p>The recommended way is to use the static <tt>createWriter</tt> methods
			provided by the <code>SequenceFile</code> to chose the preferred format.</p>

			<p>The {@link Reader} acts as the bridge and can read any of the above
			<code>SequenceFile</code> formats.</p>

			<h4 id="Formats">SequenceFile Formats</h4>

			<p>Essentially there are 3 different formats for <code>SequenceFile</code>s
			depending on the <code>CompressionType</code> specified. All of them share a
			<a href="#Header">common header</a> described below.

			<h5 id="Header">SequenceFile Header</h5>
			<ul>
			<li>
			version - 3 bytes of magic header <b>SEQ</b>, followed by 1 byte of actual
			version number (e.g. SEQ4 or SEQ6)
			</li>
			<li>
			keyClassName -key class
			</li>
			<li>
			valueClassName - value class
			</li>
			<li>
			compression - A boolean which specifies if compression is turned on for
			keys/values in this file.
			</li>
			<li>
			blockCompression - A boolean which specifies if block-compression is
			turned on for keys/values in this file.
			</li>
			<li>
			compression codec - <code>CompressionCodec</code> class which is used for
			compression of keys and/or values (if compression is
			enabled).
			</li>
			<li>
			metadata - {@link Metadata} for this file.
			</li>
			<li>
			sync - A sync marker to denote end of the header.
			</li>
			</ul>

			<h5 id="#UncompressedFormat">Uncompressed SequenceFile Format</h5>
			<ul>
			<li>
			<a href="#Header">Header</a>
			</li>
			<li>
			Record
			<ul>
			<li>Record length</li>
			<li>Key length</li>
			<li>Key</li>
			<li>Value</li>
			</ul>
			</li>
			<li>
			A sync-marker every few <code>100</code> bytes or so.
			</li>
			</ul>

			<h5 id="#RecordCompressedFormat">Record-Compressed SequenceFile Format</h5>
			<ul>
			<li>
			<a href="#Header">Header</a>
			</li>
			<li>
			Record
			<ul>
			<li>Record length</li>
			<li>Key length</li>
			<li>Key</li>
			<li><i>Compressed</i> Value</li>
			</ul>
			</li>
			<li>
			A sync-marker every few <code>100</code> bytes or so.
			</li>
			</ul>

			<h5 id="#BlockCompressedFormat">Block-Compressed SequenceFile Format</h5>
			<ul>
			<li>
			<a href="#Header">Header</a>
			</li>
			<li>
			Record <i>Block</i>
			<ul>
			<li>Compressed key-lengths block-size</li>
			<li>Compressed key-lengths block</li>
			<li>Compressed keys block-size</li>
			<li>Compressed keys block</li>

			<li>Compressed value-lengths block</li>
			<li>Compressed values block-size</li>
			<li>Compressed values block</li>
			</ul>
			</li>
			<li>
			A sync-marker every few <code>100</code> bytes or so.
			</li>
			</ul>

			<p>The compressed blocks of key lengths and value lengths consist of the
			actual lengths of individual keys/values encoded in ZeroCompressedInteger
			format.</p>

			<li>Seek by key or by file offset.
			</ul>
			The memory footprint of a TFile includes the following:
			<ul>
			<li>Some constant overhead of reading or writing a compressed block.
			<ul>
			<li>Each compressed block requires one compression/decompression codec for
			I/O.
			<li>Temporary space to buffer the key.
			<li>Temporary space to buffer the value (for TFile.Writer only). Values are
			chunk encoded, so that we buffer at most one chunk of user data. By default,
			the chunk buffer is 1MB. Reading chunked value does not require additional
			memory.
			</ul>
			<li>TFile index, which is proportional to the total number of Data Blocks.
			The total amount of memory needed to hold the index can be estimated as
			(56+AvgKeySize)*NumBlocks.
			<li>MetaBlock index, which is proportional to the total number of Meta
			Blocks.The total amount of memory needed to hold the index for Meta Blocks
			can be estimated as (40+AvgMetaBlockName)*NumMetaBlock.
			</ul>
			<p>
			The behavior of TFile can be customized by the following variables through
			Configuration:
			<ul>
			<li><b>tfile.io.chunk.size</b>: Value chunk size. Integer (in bytes). Default
			to 1MB. Values of the length less than the chunk size is guaranteed to have
			known value length in read time (See
			{@link TFile.Reader.Scanner.Entry#isValueLengthKnown()}).
			<li><b>tfile.fs.output.buffer.size</b>: Buffer size used for
			FSDataOutputStream. Integer (in bytes). Default to 256KB.
			<li><b>tfile.fs.input.buffer.size</b>: Buffer size used for
			FSDataInputStream. Integer (in bytes). Default to 256KB.
			</ul>
			<p>
			Suggestions on performance optimization.
			<ul>
			<li>Minimum block size. We recommend a setting of minimum block size between
			256KB to 1MB for general usage. Larger block size is preferred if files are
			primarily for sequential access. However, it would lead to inefficient random
			access (because there are more data to decompress). Smaller blocks are good
			for random access, but require more memory to hold the block index, and may
			be slower to create (because we must flush the compressor stream at the
			conclusion of each data block, which leads to an FS I/O flush). Further, due
			to the internal caching in Compression codec, the smallest possible block
			size would be around 20KB-30KB.
			<li>The current implementation does not offer true multi-threading for
			reading. The implementation uses FSDataInputStream seek()+read(), which is
			shown to be much faster than positioned-read call in single thread mode.
			However, it also means that if multiple threads attempt to access the same
			TFile (using multiple scanners) simultaneously, the actual I/O is carried out
			sequentially even if they access different DFS blocks.
			<li>Compression codec. Use "none" if the data is not very compressable (by
			compressable, I mean a compression ratio at least 2:1). Generally, use "lzo"
			as the starting point for experimenting. "gz" overs slightly better
			compression ratio over "lzo" but requires 4x CPU to compress and 2x CPU to
			decompress, comparing to "lzo".
			<li>File system buffering, if the underlying FSDataInputStream and
			FSDataOutputStream is already adequately buffered; or if applications
			reads/writes keys and values in large buffers, we can reduce the sizes of
			input/output buffering in TFile layer by setting the configuration parameters
			"tfile.fs.input.buffer.size" and "tfile.fs.output.buffer.size".
			</ul>

			<![CDATA[This package defines an API for reporting performance metric information.
			<p/>
			The API is abstract so that it can be implemented on top of
			a variety of metrics client libraries. The choice of
			client library is a configuration option, and different
			modules within the same application can use
			different metrics implementation libraries.
			<p/>
			Sub-packages:
			<dl>
			<dt><code>org.apache.hadoop.metrics.spi</code></dt>
			<dd>The abstract Server Provider Interface package. Those wishing to
			integrate the metrics API with a particular metrics client library should
			extend this package.</dd>

			<dt><code>org.apache.hadoop.metrics.file</code></dt>
			<dd>An implementation package which writes the metric data to
			a file, or sends it to the standard output stream.</dd>

			<dt> <code>org.apache.hadoop.metrics.ganglia</code></dt>
			<dd>An implementation package which sends metric data to
			<a href="http://ganglia.sourceforge.net/">Ganglia</a>.</dd>
			</dl>

			<h3>Introduction to the Metrics API</h3>

			Here is a simple example of how to use this package to report a single
			metric value:
			<pre>
			private ContextFactory contextFactory = ContextFactory.getFactory();

			void reportMyMetric(float myMetric) {
			MetricsContext myContext = contextFactory.getContext("myContext");
			MetricsRecord myRecord = myContext.getRecord("myRecord");
			myRecord.setMetric("myMetric", myMetric);
			myRecord.update();
			}
			</pre>

			In this example there are three names:
			<dl>
			<dt><i>myContext</i></dt>
			<dd>The context name will typically identify either the application, or else a
			module within an application or library.</dd>

			<dt><i>myRecord</i></dt>
			<dd>The record name generally identifies some entity for which a set of
			metrics are to be reported. For example, you could have a record named
			"cacheStats" for reporting a number of statistics relating to the usage of
			some cache in your application.</dd>

			<dt><i>myMetric</i></dt>
			<dd>This identifies a particular metric. For example, you might have metrics
			named "cache_hits" and "cache_misses".
			</dd>
			</dl>

			<h3>Tags</h3>

			In some cases it is useful to have multiple records with the same name. For
			example, suppose that you want to report statistics about each disk on a computer.
			In this case, the record name would be something like "diskStats", but you also
			need to identify the disk which is done by adding a <i>tag</i> to the record.
			The code could look something like this:
			<pre>
			private MetricsRecord diskStats =
			contextFactory.getContext("myContext").getRecord("diskStats");

			void reportDiskMetrics(String diskName, float diskBusy, float diskUsed) {
			diskStats.setTag("diskName", diskName);
			diskStats.setMetric("diskBusy", diskBusy);
			diskStats.setMetric("diskUsed", diskUsed);
			diskStats.update();
			}
			</pre>

			<h3>Buffering and Callbacks</h3>

			Data is not sent immediately to the metrics system when
			<code>MetricsRecord.update()</code> is called. Instead it is stored in an
			internal table, and the contents of the table are sent periodically.
			This can be important for two reasons:
			<ol>
			<li>It means that a programmer is free to put calls to this API in an
			inner loop, since updates can be very frequent without slowing down
			the application significantly.</li>
			<li>Some implementations can gain efficiency by combining many metrics
			into a single UDP message.</li>
			</ol>

			The API provides a timer-based callback via the
			<code>registerUpdater()</code> method. The benefit of this
			versus using <code>java.util.Timer</code> is that the callbacks will be done
			immediately before sending the data, making the data as current as possible.

			<h3>Configuration</h3>

			It is possible to programmatically examine and modify configuration data
			before creating a context, like this:
			<pre>
			ContextFactory factory = ContextFactory.getFactory();
			... examine and/or modify factory attributes ...
			MetricsContext context = factory.getContext("myContext");
			</pre>
			The factory attributes can be examined and modified using the following
			<code>ContextFactory</code>methods:
			<ul>
			<li><code>Object getAttribute(String attributeName)</code></li>
			<li><code>String[] getAttributeNames()</code></li>
			<li><code>void setAttribute(String name, Object value)</code></li>
			<li><code>void removeAttribute(attributeName)</code></li>
			</ul>

			<p/>
			<code>ContextFactory.getFactory()</code> initializes the factory attributes by
			reading the properties file <code>hadoop-metrics.properties</code> if it exists
			on the class path.

			<p/>
			A factory attribute named:
			<pre>
			<i>contextName</i>.class
			</pre>
			should have as its value the fully qualified name of the class to be
			instantiated by a call of the <code>CodeFactory</code> method
			<code>getContext(<i>contextName</i>)</code>. If this factory attribute is not
			specified, the default is to instantiate
			<code>org.apache.hadoop.metrics.file.FileContext</code>.

			<p/>
			Other factory attributes are specific to a particular implementation of this
			API and are documented elsewhere. For example, configuration attributes for
			the file and Ganglia implementations can be found in the javadoc for
			their respective packages.]]>

			<h2>Introduction</h2>

			Software systems of any significant complexity require mechanisms for data
			interchange with the outside world. These interchanges typically involve the
			marshaling and unmarshaling of logical units of data to and from data streams
			(files, network connections, memory buffers etc.). Applications usually have
			some code for serializing and deserializing the data types that they manipulate
			embedded in them. The work of serialization has several features that make
			automatic code generation for it worthwhile. Given a particular output encoding
			(binary, XML, etc.), serialization of primitive types and simple compositions
			of primitives (structs, vectors etc.) is a very mechanical task. Manually
			written serialization code can be susceptible to bugs especially when records
			have a large number of fields or a record definition changes between software
			versions. Lastly, it can be very useful for applications written in different
			programming languages to be able to share and interchange data. This can be
			made a lot easier by describing the data records manipulated by these
			applications in a language agnostic manner and using the descriptions to derive
			implementations of serialization in multiple target languages.

			This document describes Hadoop Record I/O, a mechanism that is aimed
			at
			<ul>
			<li> enabling the specification of simple serializable data types (records)
			<li> enabling the generation of code in multiple target languages for
			marshaling and unmarshaling such types
			<li> providing target language specific support that will enable application
			programmers to incorporate generated code into their applications
			</ul>

			The goals of Hadoop Record I/O are similar to those of mechanisms such as XDR,
			ASN.1, PADS and ICE. While these systems all include a DDL that enables
			the specification of most record types, they differ widely in what else they
			focus on. The focus in Hadoop Record I/O is on data marshaling and
			multi-lingual support. We take a translator-based approach to serialization.
			Hadoop users have to describe their data in a simple data description
			language. The Hadoop DDL translator rcc generates code that users
			can invoke in order to read/write their data from/to simple stream
			abstractions. Next we list explicitly some of the goals and non-goals of
			Hadoop Record I/O.


			<h3>Goals</h3>

			<ul>
			<li> Support for commonly used primitive types. Hadoop should include as
			primitives commonly used builtin types from programming languages we intend to
			support.

			<li> Support for common data compositions (including recursive compositions).
			Hadoop should support widely used composite types such as structs and
			vectors.

			<li> Code generation in multiple target languages. Hadoop should be capable of
			generating serialization code in multiple target languages and should be
			easily extensible to new target languages. The initial target languages are
			C++ and Java.

			<li> Support for generated target languages. Hadooop should include support
			in the form of headers, libraries, packages for supported target languages
			that enable easy inclusion and use of generated code in applications.

			<li> Support for multiple output encodings. Candidates include
			packed binary, comma-separated text, XML etc.

			<li> Support for specifying record types in a backwards/forwards compatible
			manner. This will probably be in the form of support for optional fields in
			records. This version of the document does not include a description of the
			planned mechanism, we intend to include it in the next iteration.

			</ul>

			<h3>Non-Goals</h3>

			<ul>
			<li> Serializing existing arbitrary C++ classes.
			<li> Serializing complex data structures such as trees, linked lists etc.
			<li> Built-in indexing schemes, compression, or check-sums.
			<li> Dynamic construction of objects from an XML schema.
			</ul>

			The remainder of this document describes the features of Hadoop record I/O
			in more detail. Section 2 describes the data types supported by the system.
			Section 3 lays out the DDL syntax with some examples of simple records.
			Section 4 describes the process of code generation with rcc. Section 5
			describes target language mappings and support for Hadoop types. We include a
			fairly complete description of C++ mappings with intent to include Java and
			others in upcoming iterations of this document. The last section talks about
			supported output encodings.


			<h2>Data Types and Streams</h2>

			This section describes the primitive and composite types supported by Hadoop.
			We aim to support a set of types that can be used to simply and efficiently
			express a wide range of record types in different programming languages.

			<h3>Primitive Types</h3>

			For the most part, the primitive types of Hadoop map directly to primitive
			types in high level programming languages. Special cases are the
			ustring (a Unicode string) and buffer types, which we believe
			find wide use and which are usually implemented in library code and not
			available as language built-ins. Hadoop also supplies these via library code
			when a target language built-in is not present and there is no widely
			adopted "standard" implementation. The complete list of primitive types is:

			<ul>
			<li> byte: An 8-bit unsigned integer.
			<li> boolean: A boolean value.
			<li> int: A 32-bit signed integer.
			<li> long: A 64-bit signed integer.
			<li> float: A single precision floating point number as described by
			IEEE-754.
			<li> double: A double precision floating point number as described by
			IEEE-754.
			<li> ustring: A string consisting of Unicode characters.
			<li> buffer: An arbitrary sequence of bytes.
			</ul>


			<h3>Composite Types</h3>
			Hadoop supports a small set of composite types that enable the description
			of simple aggregate types and containers. A composite type is serialized
			by sequentially serializing it constituent elements. The supported
			composite types are:

			<ul>

			<li> record: An aggregate type like a C-struct. This is a list of
			typed fields that are together considered a single unit of data. A record
			is serialized by sequentially serializing its constituent fields. In addition
			to serialization a record has comparison operations (equality and less-than)
			implemented for it, these are defined as memberwise comparisons.

			<li>vector: A sequence of entries of the same data type, primitive
			or composite.

			<li> map: An associative container mapping instances of a key type to
			instances of a value type. The key and value types may themselves be primitive
			or composite types.

			</ul>

			<h3>Streams</h3>

			Hadoop generates code for serializing and deserializing record types to
			abstract streams. For each target language Hadoop defines very simple input
			and output stream interfaces. Application writers can usually develop
			concrete implementations of these by putting a one method wrapper around
			an existing stream implementation.


			<h2>DDL Syntax and Examples</h2>

			We now describe the syntax of the Hadoop data description language. This is
			followed by a few examples of DDL usage.

			<h3>Hadoop DDL Syntax</h3>

			<pre><code>
			recfile = include module record
			include = "include" path
			path = (relative-path / absolute-path)
			module = "module" module-name
			module-name = name *("." name)
			record := "class" name "{" 1*(field) "}"
			field := type name ";"
			name := ALPHA (ALPHA / DIGIT / "_" )*
			type := (ptype / ctype)
			ptype := ("byte" / "boolean" / "int" \|
			"long" / "float" / "double"
			"ustring" / "buffer")
			ctype := (("vector" "<" type ">") /
			("map" "<" type "," type ">" ) ) / name)
			</code></pre>

			A DDL file describes one or more record types. It begins with zero or
			more include declarations, a single mandatory module declaration
			followed by zero or more class declarations. The semantics of each of
			these declarations are described below:

			<ul>

			<li>include: An include declaration specifies a DDL file to be
			referenced when generating code for types in the current DDL file. Record types
			in the current compilation unit may refer to types in all included files.
			File inclusion is recursive. An include does not trigger code
			generation for the referenced file.

			<li> module: Every Hadoop DDL file must have a single module
			declaration that follows the list of includes and precedes all record
			declarations. A module declaration identifies a scope within which
			the names of all types in the current file are visible. Module names are
			mapped to C++ namespaces, Java packages etc. in generated code.

			<li> class: Records types are specified through class
			declarations. A class declaration is like a Java class declaration.
			It specifies a named record type and a list of fields that constitute records
			of the type. Usage is illustrated in the following examples.

			</ul>

			<h3>Examples</h3>

			<ul>
			<li>A simple DDL file links.jr with just one record declaration.
			<pre><code>
			module links {
			class Link {
			ustring URL;
			boolean isRelative;
			ustring anchorText;
			};
			}
			</code></pre>

			<li> A DDL file outlinks.jr which includes another
			<pre><code>
			include "links.jr"

			module outlinks {
			class OutLinks {
			ustring baseURL;
			vector<links.Link> outLinks;
			};
			}
			</code></pre>
			</ul>

			<h2>Code Generation</h2>

			The Hadoop translator is written in Java. Invocation is done by executing a
			wrapper shell script named named rcc. It takes a list of
			record description files as a mandatory argument and an
			optional language argument (the default is Java) --language or
			-l. Thus a typical invocation would look like:
			<pre><code>
			$ rcc -l C++ <filename> ...
			</code></pre>


			<h2>Target Language Mappings and Support</h2>

			For all target languages, the unit of code generation is a record type.
			For each record type, Hadoop generates code for serialization and
			deserialization, record comparison and access to record members.

			<h3>C++</h3>

			Support for including Hadoop generated C++ code in applications comes in the
			form of a header file recordio.hh which needs to be included in source
			that uses Hadoop types and a library librecordio.a which applications need
			to be linked with. The header declares the Hadoop C++ namespace which defines
			appropriate types for the various primitives, the basic interfaces for
			records and streams and enumerates the supported serialization encodings.
			Declarations of these interfaces and a description of their semantics follow:

			<pre><code>
			namespace hadoop {

			enum RecFormat { kBinary, kXML, kCSV };

			class InStream {
			public:
			virtual ssize_t read(void *buf, size_t n) = 0;
			};

			class OutStream {
			public:
			virtual ssize_t write(const void *buf, size_t n) = 0;
			};

			class IOError : public runtime_error {
			public:
			explicit IOError(const std::string& msg);
			};

			class IArchive;
			class OArchive;

			class RecordReader {
			public:
			RecordReader(InStream& in, RecFormat fmt);
			virtual ~RecordReader(void);

			virtual void read(Record& rec);
			};

			class RecordWriter {
			public:
			RecordWriter(OutStream& out, RecFormat fmt);
			virtual ~RecordWriter(void);

			virtual void write(Record& rec);
			};


			class Record {
			public:
			virtual std::string type(void) const = 0;
			virtual std::string signature(void) const = 0;
			protected:
			virtual bool validate(void) const = 0;

			virtual void
			serialize(OArchive& oa, const std::string& tag) const = 0;

			virtual void
			deserialize(IArchive& ia, const std::string& tag) = 0;
			};
			}
			</code></pre>

			<ul>

			<li> RecFormat: An enumeration of the serialization encodings supported
			by this implementation of Hadoop.

			<li> InStream: A simple abstraction for an input stream. This has a
			single public read method that reads n bytes from the stream into
			the buffer buf. Has the same semantics as a blocking read system
			call. Returns the number of bytes read or -1 if an error occurs.

			<li> OutStream: A simple abstraction for an output stream. This has a
			single write method that writes n bytes to the stream from the
			buffer buf. Has the same semantics as a blocking write system
			call. Returns the number of bytes written or -1 if an error occurs.

			<li> RecordReader: A RecordReader reads records one at a time from
			an underlying stream in a specified record format. The reader is instantiated
			with a stream and a serialization format. It has a read method that
			takes an instance of a record and deserializes the record from the stream.

			<li> RecordWriter: A RecordWriter writes records one at a
			time to an underlying stream in a specified record format. The writer is
			instantiated with a stream and a serialization format. It has a
			write method that takes an instance of a record and serializes the
			record to the stream.

			<li> Record: The base class for all generated record types. This has two
			public methods type and signature that return the typename and the
			type signature of the record.

			</ul>

			Two files are generated for each record file (note: not for each record). If a
			record file is named "name.jr", the generated files are
			"name.jr.cc" and "name.jr.hh" containing serialization
			implementations and record type declarations respectively.

			For each record in the DDL file, the generated header file will contain a
			class definition corresponding to the record type, method definitions for the
			generated type will be present in the '.cc' file. The generated class will
			inherit from the abstract class hadoop::Record. The DDL files
			module declaration determines the namespace the record belongs to.
			Each '.' delimited token in the module declaration results in the
			creation of a namespace. For instance, the declaration module docs.links
			results in the creation of a docs namespace and a nested
			docs::links namespace. In the preceding examples, the Link class
			is placed in the links namespace. The header file corresponding to
			the links.jr file will contain:

			<pre><code>
			namespace links {
			class Link : public hadoop::Record {
			// ....
			};
			};
			</code></pre>

			Each field within the record will cause the generation of a private member
			declaration of the appropriate type in the class declaration, and one or more
			acccessor methods. The generated class will implement the serialize and
			deserialize methods defined in hadoop::Record+. It will also
			implement the inspection methods type and signature from
			hadoop::Record. A default constructor and virtual destructor will also
			be generated. Serialization code will read/write records into streams that
			implement the hadoop::InStream and the hadoop::OutStream interfaces.

			For each member of a record an accessor method is generated that returns
			either the member or a reference to the member. For members that are returned
			by value, a setter method is also generated. This is true for primitive
			data members of the types byte, int, long, boolean, float and
			double. For example, for a int field called MyField the folowing
			code is generated.

			<pre><code>
			...
			private:
			int32_t mMyField;
			...
			public:
			int32_t getMyField(void) const {
			return mMyField;
			};

			void setMyField(int32_t m) {
			mMyField = m;
			};
			...
			</code></pre>

			For a ustring or buffer or composite field. The generated code
			only contains accessors that return a reference to the field. A const
			and a non-const accessor are generated. For example:

			<pre><code>
			...
			private:
			std::string mMyBuf;
			...
			public:

			std::string& getMyBuf() {
			return mMyBuf;

			<h4>Examples</h4>

			Suppose the inclrec.jr file contains:
			<pre><code>
			module inclrec {
			class RI {
			int I32;
			double D;
			ustring S;
			};
			}
			</code></pre>

			and the testrec.jr file contains:

			<pre><code>
			include "inclrec.jr"
			module testrec {
			class R {
			vector<float> VF;
			RI Rec;
			buffer Buf;
			};
			}
			</code></pre>

			Then the invocation of rcc such as:
			<pre><code>
			$ rcc -l c++ inclrec.jr testrec.jr
			</code></pre>
			will result in generation of four files:
			inclrec.jr.{cc,hh} and testrec.jr.{cc,hh}.

			The inclrec.jr.hh will contain:

			<pre><code>
			#ifndef _INCLREC_JR_HH_

			virtual void setI32(int32_t v) { I32 = v; }

			virtual double getD(void) const { return D; }
			virtual void setD(double v) { D = v; }

			virtual void deserialize(hadoop::IArchive& a);
			};
			} // end namespace inclrec

			#endif /* _INCLREC_JR_HH_ */

			</code></pre>

			The testrec.jr.hh file will contain:


			<pre><code>

			<h3>Java</h3>

			Code generation for Java is similar to that for C++. A Java class is generated
			for each record type with private members corresponding to the fields. Getters
			and setters for fields are also generated. Some differences arise in the
			way comparison is expressed and in the mapping of modules to packages and
			classes to files. For equality testing, an equals method is generated
			for each record type. As per Java requirements a hashCode method is also
			generated. For comparison a compareTo method is generated for each
			record type. This has the semantics as defined by the Java Comparable
			interface, that is, the method returns a negative integer, zero, or a positive
			integer as the invoked object is less than, equal to, or greater than the
			comparison parameter.

			A .java file is generated per record type as opposed to per DDL
			file as in C++. The module declaration translates to a Java
			package declaration. The module name maps to an identical Java package
			name. In addition to this mapping, the DDL compiler creates the appropriate
			directory hierarchy for the package and places the generated .java
			files in the correct directories.

			<h2>Mapping Summary</h2>

			<pre><code>
			DDL Type C++ Type Java Type

			boolean bool boolean
			byte int8_t byte
			int int32_t int
			long int64_t long
			float float float
			double double double
			ustring std::string java.lang.String
			buffer std::string org.apache.hadoop.record.Buffer
			class type class type class type
			vector<type> std::vector<type> java.util.ArrayList<type>
			map<type,type> std::map<type,type> java.util.TreeMap<type,type>
			</code></pre>

			<h2>Data encodings</h2>

			This section describes the format of the data encodings supported by Hadoop.
			Currently, three data encodings are supported, namely binary, CSV and XML.

			<h3>Binary Serialization Format</h3>

			The binary data encoding format is fairly dense. Serialization of composite
			types is simply defined as a concatenation of serializations of the constituent
			elements (lengths are included in vectors and maps).

			Composite types are serialized as follows:
			<ul>
			<li> class: Sequence of serialized members.
			<li> vector: The number of elements serialized as an int. Followed by a
			sequence of serialized elements.
			<li> map: The number of key value pairs serialized as an int. Followed
			by a sequence of serialized (key,value) pairs.
			</ul>

			Serialization of primitives is more interesting, with a zero compression
			optimization for integral types and normalization to UTF-8 for strings.
			Primitive types are serialized as follows:

			<ul>
			<li> byte: Represented by 1 byte, as is.
			<li> boolean: Represented by 1-byte (0 or 1)
			<li> int/long: Integers and longs are serialized zero compressed.
			Represented as 1-byte if -120 <= value < 128. Otherwise, serialized as a
			sequence of 2-5 bytes for ints, 2-9 bytes for longs. The first byte represents
			the number of trailing bytes, N, as the negative number (-120-N). For example,
			the number 1024 (0x400) is represented by the byte sequence 'x86 x04 x00'.
			This doesn't help much for 4-byte integers but does a reasonably good job with
			longs without bit twiddling.
			<li> float/double: Serialized in IEEE 754 single and double precision
			format in network byte order. This is the format used by Java.
			<li> ustring: Serialized as 4-byte zero compressed length followed by
			data encoded as UTF-8. Strings are normalized to UTF-8 regardless of native
			language representation.
			<li> buffer: Serialized as a 4-byte zero compressed length followed by the
			raw bytes in the buffer.
			</ul>


			<h3>CSV Serialization Format</h3>

			The CSV serialization format has a lot more structure than the "standard"
			Excel CSV format, but we believe the additional structure is useful because

			<ul>
			<li> it makes parsing a lot easier without detracting too much from legibility
			<li> the delimiters around composites make it obvious when one is reading a
			sequence of Hadoop records
			</ul>

			Serialization formats for the various types are detailed in the grammar that
			follows. The notable feature of the formats is the use of delimiters for
			indicating the certain field types.

			<ul>
			<li> A string field begins with a single quote (').
			<li> A buffer field begins with a sharp (#).
			<li> A class, vector or map begins with 's{', 'v{' or 'm{' respectively and
			ends with '}'.
			</ul>

			The CSV format can be described by the following grammar:

			<pre><code>
			record = primitive / struct / vector / map
			primitive = boolean / int / long / float / double / ustring / buffer

			boolean = "T" / "F"
			int = ["-"] 1*DIGIT
			long = ";" ["-"] 1*DIGIT
			float = ["-"] 1DIGIT "." 1DIGIT ["E" / "e" ["-"] 1*DIGIT]
			double = ";" ["-"] 1DIGIT "." 1DIGIT ["E" / "e" ["-"] 1*DIGIT]

			ustring = "'" *(UTF8 char except NULL, LF, % and , / "%00" / "%0a" / "%25" / "%2c" )

			buffer = "#" *(BYTE except NULL, LF, % and , / "%00" / "%0a" / "%25" / "%2c" )

			struct = "s{" record *("," record) "}"
			vector = "v{" [record *("," record)] "}"
			map = "m{" [*(record "," record)] "}"
			</code></pre>

			<h3>XML Serialization Format</h3>

			The XML serialization format is the same used by Apache XML-RPC
			(http://ws.apache.org/xmlrpc/types.html). This is an extension of the original
			XML-RPC format and adds some additional data types. All record I/O types are
			not directly expressible in this format, and access to a DDL is required in
			order to convert these to valid types. All types primitive or composite are
			represented by <value> elements. The particular XML-RPC type is
			indicated by a nested element in the <value> element. The encoding for
			records is always UTF-8. Primitive types are serialized as follows:

			<ul>
			<li> byte: XML tag <ex:i1>. Values: 1-byte unsigned
			integers represented in US-ASCII
			<li> boolean: XML tag <boolean>. Values: "0" or "1"
			<li> int: XML tags <i4> or <int>. Values: 4-byte
			signed integers represented in US-ASCII.
			<li> long: XML tag <ex:i8>. Values: 8-byte signed integers
			represented in US-ASCII.
			<li> float: XML tag <ex:float>. Values: Single precision
			floating point numbers represented in US-ASCII.
			<li> double: XML tag <double>. Values: Double precision
			floating point numbers represented in US-ASCII.
			<li> ustring: XML tag <;string>. Values: String values
			represented as UTF-8. XML does not permit all Unicode characters in literal
			data. In particular, NULLs and control chars are not allowed. Additionally,
			XML processors are required to replace carriage returns with line feeds and to
			replace CRLF sequences with line feeds. Programming languages that we work
			with do not impose these restrictions on string types. To work around these
			restrictions, disallowed characters and CRs are percent escaped in strings.
			The '%' character is also percent escaped.
			<li> buffer: XML tag <string&>. Values: Arbitrary binary
			data. Represented as hexBinary, each byte is replaced by its 2-byte
			hexadecimal representation.
			</ul>

			Composite types are serialized as follows:

			<ul>
			<li> class: XML tag <struct>. A struct is a sequence of
			<member> elements. Each <member> element has a <name>
			element and a <value> element. The <name> is a string that must
			match /[a-zA-Z][a-zA-Z0-9_]*/. The value of the member is represented
			by a <value> element.

			<li> vector: XML tag <array<. An <array> contains a
			single <data> element. The <data> element is a sequence of
			<value> elements each of which represents an element of the vector.

			<li> map: XML tag <array>. Same as vector.

			</ul>

			For example:

			<pre><code>
			class {
			int MY_INT; // value 5
			vector<float> MY_VEC; // values 0.1, -0.89, 2.45e4
			buffer MY_BUF; // value '\00\n\tabc%'
			}
			</code></pre>

			is serialized as

			<pre><code class="XML">
			<value>
			<struct>
			<member>
			<name>MY_INT</name>
			<value><i4>5</i4></value>
			</member>
			<member>
			<name>MY_VEC</name>
			<value>
			<array>
			<data>
			<value><ex:float>0.1</ex:float></value>
			<value><ex:float>-0.89</ex:float></value>
			<value><ex:float>2.45e4</ex:float></value>
			</data>
			</array>
			</value>
			</member>
			<member>
			<name>MY_BUF</name>
			<value><string>%00\n\tabc%25</string></value>
			</member>
			</struct>
			</value>
			</code></pre>]]>

			<![CDATA[Implements a <i>Bloom filter</i>, as defined by Bloom in 1970.
			<p>
			The Bloom filter is a data structure that was introduced in 1970 and that has been adopted by
			the networking research community in the past decade thanks to the bandwidth efficiencies that it
			offers for the transmission of set membership information between networked hosts. A sender encodes
			the information into a bit vector, the Bloom filter, that is more compact than a conventional
			representation. Computation and space costs for construction are linear in the number of elements.
			The receiver uses the filter to test whether various elements are members of the set. Though the
			filter will occasionally return a false positive, it will never return a false negative. When creating
			the filter, the sender can choose its desired point in a trade-off between the false positive rate and the size.

			<![CDATA[Implements a <i>dynamic Bloom filter</i>, as defined in the INFOCOM 2006 paper.
			<p>
			A dynamic Bloom filter (DBF) makes use of a <code>s * m</code> bit matrix but
			each of the <code>s</code> rows is a standard Bloom filter. The creation
			process of a DBF is iterative. At the start, the DBF is a <code>1 * m</code>
			bit matrix, i.e., it is composed of a single standard Bloom filter.
			It assumes that <code>n<sub>r</sub></code> elements are recorded in the
			initial bit vector, where <code>n<sub>r</sub> <= n</code> (<code>n</code> is
			the cardinality of the set <code>A</code> to record in the filter).
			<p>
			As the size of <code>A</code> grows during the execution of the application,
			several keys must be inserted in the DBF. When inserting a key into the DBF,
			one must first get an active Bloom filter in the matrix. A Bloom filter is
			active when the number of recorded keys, <code>n<sub>r</sub></code>, is
			strictly less than the current cardinality of <code>A</code>, <code>n</code>.
			If an active Bloom filter is found, the key is inserted and
			<code>n<sub>r</sub></code> is incremented by one. On the other hand, if there
			is no active Bloom filter, a new one is created (i.e., a new row is added to
			the matrix) according to the current size of <code>A</code> and the element
			is added in this new Bloom filter and the <code>n<sub>r</sub></code> value of
			this new Bloom filter is set to one. A given key is said to belong to the
			DBF if the <code>k</code> positions are set to one in one of the matrix rows.
