> Key: YARN-4350
> URL: https://issues.apache.org/jira/browse/YARN-4350
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Affects Versions: YARN-2928
> Reporter: Sangjin Lee
> Assignee: Naganarasimha G R
>
> Currently TestDistributedShell does not pass on the feature-YARN-2928 branch.
> There seem to be 2 distinct issues.
> (1) testDSShellWithoutDomainV2* tests fail sporadically
> These test fail more often than not if tested by themselves:
> {noformat}
> testDSShellWithoutDomainV2DefaultFlow(org.apache.hadoop.yarn.applications.distributedshell.TestDistributedShell)
> Time elapsed: 30.998 sec <<< FAILURE!
> java.lang.AssertionError: Application created event should be published
> atleast once expected:<1> but was:<0>
> at org.junit.Assert.fail(Assert.java:88)
> at org.junit.Assert.failNotEquals(Assert.java:743)
> at org.junit.Assert.assertEquals(Assert.java:118)
> at org.junit.Assert.assertEquals(Assert.java:555)

> org.apache.hadoop.yarn.applications.distributedshell.TestDistributedShell.testDSShellWithoutDomainV2DefaultFlow(TestDistributedShell.java:207)
> {noformat}
> They start happening after YARN-4129. I suspect this might have to do with
> some timing issue.
> (2) the whole test times out
> If you run the whole TestDistributedShell test, it times out without fail.
> This may or may not have to do with the port change introduced by YARN-2859
> (just a hunch).
