> 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)
> 	at org.apache.hadoop.yarn.applications.distributedshell.TestDistributedShell.checkTimelineV2(TestDistributedShell.java:451)
> 	at org.apache.hadoop.yarn.applications.distributedshell.TestDistributedShell.testDSShell(TestDistributedShell.java:326)
> 	at 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).
