Wangda Tan created YARN-4024:
--------------------------------

             Summary: YARN RM should avoid resolving IP when NMs doing heartbeat
                 Key: YARN-4024
                 URL: https://issues.apache.org/jira/browse/YARN-4024
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Wangda Tan
            Assignee: Wangda Tan


Currently, YARN RM NodesListManager will resolve IP address every time when node doing heartbeat. When DNS server becomes slow, NM heartbeat will be blocked and cannot make progress.
