Karthik Kambatla commented on YARN-1861:
----------------------------------------
Interesting. Good catch, Arpit. I am surprised we can run into this. Just
curious, how long have they been stuck?
When an RM transitions to standby, the RM is supposed to automatically
re-enroll itself in leader-election even if it doesn't lose its own ZK session.
If this is not the case, we should fix it. If the RM does that, there shouldn't
be a reason for both to be stuck in Standby mode.
