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>

org.apache.hadoop.yarn.server.resourcemanager.TestResourceTrackerService.testNodeRemovalUtilDecomToUntracked(TestResourceTrackerService.java:1723)

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
