Subject [jira] [Commented] (YARN-4350) TestDistributedShell fails
Date Thu, 17 Dec 2015 17:06:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15062342#comment-15062342

Naganarasimha G R commented on YARN-4350:
-----------------------------------------

Hi [~sjlee0] & [~varun_saxena],
I tried to check and reproduce it many times i was not able to reproduce it and from the logs
was not able to figure out much, but the failures are not related to the issues which we targeted
to fix as part of this jira and felt from the testcase logs there might have been some network
jitter trying to change the title and reapply the patch again !

> 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.failNotEquals(Assert.java:743)

> {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).
