Jianfei Jiang commented on HDFS-15245:
--------------------------------------
Thanks [~weichiu] and [~ayushtkn] for code review.
The RpcDetailedActivity statistics in jmx are some detail infomation. I wonder
whether it is proper to add to the main page. As a comparison, nn and dn seem
not have such detailed infomation at the home page. Hope you can give some
advice.
