Sangjin Lee created YARN-4350:
---------------------------------
Summary: 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>

{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).
