Kihwal Lee commented on HDFS-10440:
-----------------------------------
The patch looks good, waiting for the precommit to come back. I flagged it as
incompatible change as the jmx format changed.
It will be nice if we add links to datanodes in the namenode datanodes page,
but that can be done in a separate jira.

> At present, datanode web UI doesn't have much information except for node
> name and port. Propose to add more information similar to namenode UI,
> including,
> * Static info (version, block pool and cluster ID)
> * Block pools info (BP IDs, namenode address, actor states)
> * Storage info (Volumes, capacity used, reserved, left)
> * Utilities (logs)
