Subject [jira] [Commented] (HIVE-19597) TestWorkloadManager sometimes hangs
Date Fri, 01 Jun 2018 01:13:00 GMT

Sergey Shelukhin commented on HIVE-19597:
-----------------------------------------

Looks like the test event can get overwritten and never be triggered.
[~prasanth_j] can you take a look?
I'm also adding some logging to make it easier to debug.
