<!-- 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. -->

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

the configuration property mapreduce.cluster.acls.enabled to true.

<!-- 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.
