Hemanth Yamijala commented on MAPREDUCE-1082:
---------------------------------------------
Looking close. Some final comments:
- We are assuming the job statuses cannot be null in QueueInfo. I think we
should check this in setJobStatuses. If it is null, we can set an empty array.
- The test case should call APIs like setRootQueues. getQueue is not passing
through the code path change you made in JobTracker.getQueueInfoArray
> Command line UI for queues' information is broken with hierarchical queues.
