rahul k singh commented on MAPREDUCE-861:
-----------------------------------------
small correction above:
getLeafQueues is actually getLeafQueueNames().
Some more clarification in terms of names of queue:
1 . The name of the queues would be <parent>.<child>.<grandChild>.
for example:
{code:xml}
<queue>
<name>q</name>
<queue>
<name>p</name>
</queue>
</queue>
{code}
In the above example : There are 2 queues. "q" is a root level queue and "p" is
a child of "q".
The name of queue "q" would be "q";
The name of queue "p" would be "q.p".
We would always use this completely qualified name in the implementation.
Users cannot name a queue like <queue-name>.<queue-name> as "." is used as
separator.
> Modify queue configuration format and parsing to support a hierarchy of
> queues.

> MAPREDUCE-853 proposes to introduce a hierarchy of queues into the Map/Reduce
> framework. This JIRA is for defining changes to the configuration related to
> queues.
> The current format for defining a queue and its properties is as follows:
> mapred.queue.<queue-name>.<property-name>. For e.g.
> mapred.queue.<queue-name>.acl-submit-job. The reason for using this verbose
> format was to be able to reuse the Configuration parser in Hadoop. However,
> administrators currently using the queue configuration have already indicated
> a very strong desire for a more manageable format. Since, this becomes more
> unwieldy with hierarchical queues, the time may be good to introduce a new
> format for representing queue configuration.
