Íñigo Goiri commented on HDFS-15245:
------------------------------------
Thanks [~jiangjianfei], I have to say I've had to go through the raw JMX output
a bunch of times to check the state of the edits.
Having it in the UI makes it much cleaner when debugging.
Let's fix the checkstyles raised by Yetus.
Regarding detailed RPC metrics, let's open a new JIRA and do a Web UI component
to be used by all the HDFS components (NN, DN, Router, and JN).
This view could go to the "Utilities" tab of all components.
