Subject [jira] [Commented] (YARN-4350) TestDistributedShell fails
Date Mon, 07 Dec 2015 23:11:11 GMT

Vrushali C commented on YARN-4350:
----------------------------------

Hi [~Naganarasimha]

Is the patch 001 the latest patch? If we want to use a fixed port in a unit test, wondering
if we should get it from the configuration (use default if not set in config). Or consider
setting the default in a constants file used by unit tests, if there is such a file for tests.

thanks
Vrushali

> 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>

> {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).
