      Description

      When the command "./bin/mapred --config ~/tmp/conf/ queue -list" is run, it just hangs. I can see the following in the JT logs:

      2009-10-08 13:19:26,762 INFO org.apache.hadoop.ipc.Server: IPC Server handler 1 on 55555 caught: java.lang.NullPointerException

              at org.apache.hadoop.ipc.Server$Handler.run(Server.java:983)
      

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