-----------------------------------------
Hi [~sjlee0],
I have rebased YARN-3127, hope you can have a look at it once ? also for
YARN-4372 seems like it might take little bit more time(atleast i was not able
to crack it). so if its very important then we can take the approach(fixed port
got from serversocketutil) as i had mentioned in YARN-2859 and we can continue.
And once the YARN-4372 is done we can revert it back to ephemermal
port(YARN-2859 solution). Thoughts ?
> TestDistributedShell fails
> --------------------------

> 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

> 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)

> {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).
