Subject [jira] [Commented] (HDFS-10440) Improve DataNode web UI
Date Fri, 17 Jun 2016 09:18:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15335756#comment-15335756

Weiwei Yang commented on HDFS-10440:

Hello [~vinayrpet]

That's a good point, I just modified the patch to avoid of breaking compatibility, just uploaded
 [v4 patch | ^HDFS-10440.004.patch]. I added a new entry *getBPServiceActorInfo()* in DatanodeMXBean,
I tend to use this instead of getNameNodesInfo because it sounds more accurate of the information
it returns, but I am open for suggestions :) . Please help to review and let me know if this
is good to you.

> 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)
