      DataNode Web UI has been improved with new HTML5 page, showing useful information.

      Description

      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)
