    Description

      Add the nodemanager bits of MAPREDUCE-3502 to shut down the Nodemanager services. This is done by checking for fields being non-null before shutting down/closing etc, and setting the fields to null afterwards -to be resilient against re-entrancy.

      No tests other than manual review.
