-------------------------------------------

                 Key: MAPREDUCE-2756
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2756
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client, mrv2
    Affects Versions: 0.23.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans
            Priority: Minor
             Fix For: 0.23.0


If you run a pig job with UDFs that has not been recompiled for MRV2.  There are situations where pig will fail with an error message stating that Hadoop failed and did not give a reason.  There is even the possibility of deadlock if an Error is thrown and the JobControl thread dies.
