Rohith commented on YARN-2599:
------------------------------
I do agree that StandBy RM should expose jmx and metrics. I did some analysis
by comparing /jmx for active rm's and standby rm's(with private patch). All the
metrics that were listed in /jmx are consistent with Active details and standby
details. But I could not find any details when "/metrics" page when I tried
from browser's(IE,chrome and fairefox).It displayed empty page!!! . I think
/metrics details are embedded in /jmx only.
> Standby RM should also expose some jmx and metrics

> YARN-1898 redirects jmx and metrics to the Active. As discussed there, we
