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

             Summary: Unclean exit in ReplicationMonitor#run occasionally causes tests to
fail 
                 Key: HDFS-3933
                 URL: https://issues.apache.org/jira/browse/HDFS-3933
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.0.0-alpha
            Reporter: Eli Collins


I've seen the following in jenkins jobs for TestHadoopArchives and  TestBlockTokenWithDFS.
We're not getting the initial ExitException thrown by ReplicationMonitor, just the log of
the ExitException in MiniDFSCluster shutdown. Looks like the ExitException has no message
so the throwable that resulted in the ExitException has no message, in which case it would
be useful to capture the whole stacktrace of the throwable.
