             Summary: Two RMNodes for the same NodeId are used in RM sometimes after NM is reconnected.
                 Key: YARN-3802
                 URL: https://issues.apache.org/jira/browse/YARN-3802
             Project: Hadoop YARN
          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.
