Jonathan Eagles created MAPREDUCE-5607:
------------------------------------------

             Summary: Backport MAPREDUCE-5086 - MR app master deletes staging dir when sent a reboot command from the RM
                 Key: MAPREDUCE-5607
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5607
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
            Reporter: Jonathan Eagles
            Assignee: Jian He
             Fix For: 2.1.0-beta


If the RM is restarted when the MR job is running, then it sends a reboot command to the job. The job ends up deleting the staging dir and that causes the next attempt to fail.
