The distributed cache cleanup thread has no monitoring to check to see if it has dies for some
reason
-----------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-2495
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2495
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: distributed-cache
    Affects Versions: 0.21.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans
            Priority: Minor


The cleanup thread in the distributed cache handles IOExceptions and the like correctly, but
just to be a bit more defensive it would be good to monitor the thread, and check that it
is still alive regularly, so that the distributed cache does not fill up the entire disk on
the node.
