             Summary: TestResourceTrackerService.testNodeRemovalNormally: Shutdown nodes should be 0 now expected: <1> but was: <0>
                 Key: YARN-11390
                 URL: https://issues.apache.org/jira/browse/YARN-11390
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
            Reporter: Bence Kosztolnik
            Assignee: Bence Kosztolnik


Some times the TestResourceTrackerService.{*}testNodeRemovalNormally{*} fails with the following message


java.lang.AssertionError: Shutdown nodes should be 0 now expected:<1> but was:<0>
	at org.apache.hadoop.yarn.server.resourcemanager.TestResourceTrackerService.testNodeRemovalUtilDecomToUntracked(TestResourceTrackerService.java:1723)
	at org.apache.hadoop.yarn.server.resourcemanager.TestResourceTrackerService.testNodeRemovalUtil(TestResourceTrackerService.java:1685)
	at org.apache.hadoop.yarn.server.resourcemanager.TestResourceTrackerService.testNodeRemovalNormally(TestResourceTrackerService.java:1530)
This can happen in case if the hardcoded 1s sleep in the test not enough for proper shut down.

To fix this issue we should poll the cluster status with a time out, and see the cluster can reach the expected state
