Subject [jira] [Created] (MAPREDUCE-4157) ResourceManager should not kill apps that are well behaved

ResourceManager should not kill apps that are well behaved
----------------------------------------------------------

                 Key: MAPREDUCE-4157
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4157
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: mrv2
    Affects Versions: 0.23.3
            Reporter: Jason Lowe
            Assignee: Jason Lowe


Currently when the ApplicationMaster unregisters with the ResourceManager, the RM kills (via
the NMs) all the active containers for an application.  This introduces a race where the AM
may be trying to clean up and may not finish before it is killed.  The RM should give the
AM a chance to exit cleanly on its own rather than always race with a pending kill on shutdown.
