<!-- This is the template for queue configuration. The format supports nesting of
queues within queues - a feature called hierarchical queues. All queues are
defined within the 'queues' tag which is the top level element for this
XML document. The queue acls configured here for different queues are
checked for authorization only if the configuration property
mapreduce.cluster.acls.enabled is set to true. -->
<queues>
<!-- Configuration for a queue is specified by defining a 'queue' element. -->
<queue>
<!-- Name of a queue. Queue name cannot contain a ':' -->
<name>default</name>
<!-- properties for a queue, typically used by schedulers,
can be defined here -->
<properties>
</properties>
<!-- State of the queue. If running, the queue will accept new jobs.
If stopped, the queue will not accept new jobs. -->
<state>running</state>
<!-- Specifies the ACLs to check for submitting jobs to this queue.
If set to '*', it allows all users to submit jobs to the queue.
If set to ' '(i.e. space), no user will be allowed to do this
operation. The default value for any queue acl is ' '.
For specifying a list of users and groups the format to use is
user1,user2 group1,group2
It is only used if authorization is enabled in Map/Reduce by setting
the configuration property mapreduce.cluster.acls.enabled to true.
Irrespective of this ACL configuration, the user who started the
cluster and cluster administrators configured via
mapreduce.cluster.administrators can do this operation. -->
<acl-submit-job> </acl-submit-job>
<!-- Specifies the ACLs to check for viewing and modifying jobs in this
queue. Modifications include killing jobs, tasks of jobs or changing
priorities.
If set to '*', it allows all users to view, modify jobs of the queue.
If set to ' '(i.e. space), no user will be allowed to do this
operation.
For specifying a list of users and groups the format to use is
user1,user2 group1,group2
It is only used if authorization is enabled in Map/Reduce by setting
the configuration property mapreduce.cluster.acls.enabled to true.
Irrespective of this ACL configuration, the user who started the
cluster and cluster administrators configured via
mapreduce.cluster.administrators can do the above operations on all
the jobs in all the queues. The job owner can do all the above
operations on his/her job irrespective of this ACL configuration. -->
<acl-administer-jobs> </acl-administer-jobs>
</queue>
<!-- Here is a sample of a hierarchical queue configuration
where q2 is a child of q1. In this example, q2 is a leaf level
queue as it has no queues configured within it. Currently, ACLs
and state are only supported for the leaf level queues.
Note also the usage of properties for the queue q2.
<queue>
<name>q1</name>
<queue>
<name>q2</name>
<properties>
<property key="capacity" value="20"/>
<property key="user-limit" value="30"/>
</properties>
</queue>
</queue>
-->
