Sunil Govindan commented on YARN-2599:
--------------------------------------
Thanks [~bibinchundatt]
I do not think its a compatibility issue. Fundamentally current behaviour is
broken. In one of old Jira prior to HA, I could see that each process was
having its own jmx. So redirect on jmx was not correct. I am pulling this only
to trunk and mark a note about same.
I could not get the metrics servlet. I ll dig in a bit. This seems very old,
and I am not sure whether its already moved out or not,
> Standby RM should also expose some jmx and metrics
