[jira] [Created] (YARN-4756) Unnecessary wait in Node Status Updater during reboot

Eric Badger created YARN-4756:
---------------------------------

             Summary: Unnecessary wait in Node Status Updater during reboot
                 Key: YARN-4756
                 URL: https://issues.apache.org/jira/browse/YARN-4756
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Eric Badger
            Assignee: Eric Badger


The Node Status Updater thread waits for the isStopped variable to be set to true, but it is waiting for the next heartbeat. During a reboot, the next heartbeat will not come and so the thread waits for a timeout. Instead, we should notify the thread to continue so that it can check the isStopped variable and exit without having to wait for a timeout.
