- <!-- 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. -->

-
- <!-- 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>

- <!-- State of the queue. If running, the queue will accept new jobs.
- If stopped, the queue will not accept new jobs. -->

- <!-- 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. -->

- <!-- Specifies the ACLs to check for viewing and modifying jobs in this
- queue. Modifications include killing jobs, tasks of jobs or changing

-
- Irrespective of this ACL configuration, the user who started the
- cluster and cluster administrators configured via

- the jobs in all the queues. The job owner can do all the above
- operations on his/her job irrespective of this ACL configuration. -->

- <!-- 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

- Note also the usage of properties for the queue q2.
- <queue>
