rahul k singh commented on MAPREDUCE-861:
-----------------------------------------
the name of getQueues method in QueueManager would be changed to getLeafQueues.
>From the code point of view we see following places where things would be
>impacted.
1. DynamicPriorityScheduler.java line : 80 ., line : 240
2. JobTracker.java line : 3310
3. TestQueueManager line: 56
4. CapacityTaskScheduler line: 1045 , line: 1102
Ill go ahead and change the call to getQueues to getLeafQueues. The
getLeafQueues would return list of queues to which job can be submitted.
P.S: For the first cut we are not allowing to submit the job at higher level
queues. they are just the logical grouping of the leaf level queues.
> 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.
