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

             Summary: Check NodeManager's validity based on hostname(IP) and port
                 Key: YARN-4260
                 URL: https://issues.apache.org/jira/browse/YARN-4260
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: resourcemanager
    Affects Versions: 2.7.1
            Reporter: jaehoon ko


There can be situations where multiple NMs are running on the same host; emulating multi-host YARN cluster on one host, deploying dockerized NMs that share network stack. In such cases, RM should be able to distinguish NMs running on the same host. However, current implementation checks validity of NM based only on hostname (NodesListManager.isValidNode()). So it is not possible to distinguish a specific NM from other NMs on the same host.
