> 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)
