Command line UI for queues' information is broken with hierarchical queues.
---------------------------------------------------------------------------
Key: MAPREDUCE-1082
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1082
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: client, jobtracker
Affects Versions: 0.21.0
Reporter: Vinod K V
Priority: Blocker
Fix For: 0.21.0
When the command "./bin/mapred --config ~/tmp/conf/ queue -list" is run, it
just hangs. I can see the following in the JT logs:
{code}

Same is the case with "./bin/mapred --config ~/tmp/conf/ queue -info
<any-container-queue>"
