[jira] [Created] (MAPREDUCE-5154) staging directory deletion fails because delegation tokens have been cancelled

Sandy Ryza created MAPREDUCE-5154:
-------------------------------------

             Summary: staging directory deletion fails because delegation tokens have been cancelled
                 Key: MAPREDUCE-5154
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5154
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
    Affects Versions: 2.0.3-alpha
            Reporter: Sandy Ryza
            Assignee: Sandy Ryza


In a secure setup, the jobtracker needs the job's delegation tokens to delete the staging directory.  MAPREDUCE-4850 made it so that job cleanup staging directory deletion occurs asynchronously, so that it could order it with system directory deletion.  This introduced the issue that a job's delegation tokens could be cancelled before the cleanup thread got around to deleting it, causing the deletion to fail.
