Quick Start

This section describes how to run YCSB on Accumulo.

1. Start Accumulo

See the Accumulo Documentation for details on installing and running Accumulo.

Before running the YCSB test you must create the Accumulo table. Again see the Accumulo Documentation for details. The default table name is ycsb.

2. Set Up YCSB

Git clone YCSB and compile:

git clone http://github.com/brianfrankcooper/YCSB.git
cd YCSB
mvn -pl com.yahoo.ycsb:aerospike-binding -am clean package

3. Load Data and Run Tests

Load the data:

./bin/ycsb load accumulo -s -P workloads/workloada \
     -p accumulo.zooKeepers=localhost \
     -p accumulo.columnFamily=ycsb \
     -p accumulo.instanceName=ycsb \
     -p accumulo.username=user \
     -p accumulo.password=supersecret \
     > outputLoad.txt

Run the workload test:

./bin/ycsb run accumulo -s -P workloads/workloada  \
     -p accumulo.zooKeepers=localhost \
     -p accumulo.columnFamily=ycsb \
     -p accumulo.instanceName=ycsb \
     -p accumulo.username=user \
     -p accumulo.password=supersecret \
     > outputLoad.txt
