Subject [jira] [Commented] (YARN-5556) CapacityScheduler: Support deleting queues without requiring a RM restart

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

Hi [~naganarasimha_gr@apache.org],

When I working on other tickets, I found a test failure:

{code}
java.lang.AssertionError: Expected to NOT throw exception when refresh queue tries to delete
a queue WITHOUT running apps
	at org.junit.Assert.fail(Assert.java:88)
	at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.TestCapacityScheduler.testRefreshQueuesWithQueueDelete(TestCapacityScheduler.java:3870)
{code}

Is it an intermittent failure or it is caused by other changes?

See: https://builds.apache.org/job/PreCommit-YARN-Build/14735/testReport/org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity/TestCapacityScheduler/testRefreshQueuesWithQueueDelete/

Thanks.

> Today, we could add or modify queues without restarting the RM, via a CS refresh. But
for deleting queue, we have to restart the ResourceManager. We could support for deleting
queues without requiring a RM restart
