NPE in JobClient querying an (empty) queue
------------------------------------------

                 Key: MAPREDUCE-1587
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1587
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client
    Affects Versions: 0.22.0
         Environment: Suse Linux Java 6u15
            Reporter: Steve Loughran
            Priority: Minor


Getting a stack trace on a VM-hosted cluster with an empty queue. Thought maybe it was the -verbose option, but no, remove that and I still see it.
