Subject [jira] [Commented] (HBASE-14378) Get TestAccessController* passing again on branch-1
Date Fri, 25 Sep 2015 05:17:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14907594#comment-14907594

stack commented on HBASE-14378:
-------------------------------

Thanks [~apurtell]  Was able to do direct correlation between the tests edited here and their
going zombie.

I think I made them zombies by reducing the priority count in first place -- but they seemed
to be zomby-fiying then because too many threads. Hopefully this whack-a-mole is leading somewhere.

> TestAccessController* are failing reliably on branch-1. They go zombie. I learned that
setting the junit test timeout facility on the class doesn't make the zombie timeout nor does
setting a timeout on each test turn zombies to test failures; the test goes zombie on the
way out in the tear down of the cluster.
> Digging, we are out of handlers... all are occupied.
> 3dacee6 HBASE-14290 Spin up less threads in tests cut the default thread count to 3 from
10. Putting the value back on these tests seems to make them pass reliably when I run locally.
 For good measure, I'll add in the timeouts .
