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

             Summary: Two RMNodes for the same NodeId are used in RM sometimes after NM is
reconnected.
                 Key: MAPREDUCE-6398
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6398
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.7.0
            Reporter: zhihai xu
            Assignee: zhihai xu


Two RMNodes for the same NodeId are used in RM sometimes after NM is reconnected. Scheduler
and RMContext use different RMNode reference for the same NodeId sometimes after NM is reconnected,
which is not correct. Scheduler and RMContext should always use same RMNode reference for
the same NodeId.
