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

             Summary: TestNodeStatusUpdater does not handle early failure in threads
                 Key: YARN-10468
                 URL: https://issues.apache.org/jira/browse/YARN-10468
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Ahmed Hussein


While investigating HADOOP-17314, I found that the 

* TestNodeStatusUpdater#testNMRegistration() will continue running {{while (heartBeatID <= 3 && waitCount++ != 200) {}} even though the nm thread could already be dead.  the unit should detect that the nm has died and terminates sooner to release resources for other tests.
* TestNodeStatusUpdater#testNMRMConnectionConf(). Same problem as described above.
