[jira] [Created] (MAPREDUCE-5989) Add DeletionService in AM

Varun Saxena created MAPREDUCE-5989:
---------------------------------------

             Summary: Add DeletionService in AM
                 Key: MAPREDUCE-5989
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5989
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: applicationmaster
            Reporter: Varun Saxena
            Assignee: Varun Saxena


In AM, for graceful cleanup, I propose addition of a DeletionService which will do the following :
1. Cleanup of failed tasks (temporary data need not occupy space till NM's Deletion Service is invoked)
2. Staging directory deletion (During AM shutdown, its better to place staging dir cleanup in Deletion Service: Refer to MAPREDUCE-4841 )
