Deadlock in RM
We are observing a repetitive issue with hadoop 2.6.0/HDP 2.2 with RM
capacity scheduler threads getting into a deadlock. It appears that the RM
UI scheduler flow for getResourceUsageReport is triggering the deadlock.
Have raised a jira for the same -
*https://issues.apache.org/jira/browse/YARN-3346
<https://issues.apache.org/jira/browse/YARN-3346>*. Can someone please take
a look and get back with your thoughts on this.
Thanks
Suma

Wangda Tan commented on the JIRA saying that this is same as YARN-3251 that is already fixed. But it's not part of any release yet.
