---------------------------------------

             Summary: Allow setting yarn.nodemanager.delete.debug-delay-sec on a per-job basis
                 Key: MAPREDUCE-4284
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4284
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
            Reporter: Ahmed Radwan
            Assignee: Ahmed Radwan


The yarn.nodemanager.delete.debug-delay-sec property is helpful in debugging jobs (inspecting
container logs/local dirs after the job finishes). Currently it is a nodemanager property
and changing it requires restarting the nodemanager. In a production cluster this can be a
real problem. It is better to have this property set on a per-job basis and not requiring
the restart of nodemanagers.
