Subject [jira] [Commented] (HDFS-10440) Improve DataNode web UI
Date Tue, 31 May 2016 08:06:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15307402#comment-15307402

Weiwei Yang commented on HDFS-10440:

I have a patch ready to add datanode UI with basic information, including block pools and
storage. Please check [#datanode_html.001.jpg] and [#datanode_utilities.001.jpg]. The patch
can be applied to both trunk and branch-2. This patch is created based on existing datanode
JMX, I think it's a good place to start.

> 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)
> * Running state (active, decommissioning, decommissioned or lost etc)
> * Summary (blocks, capacity, storage etc)
> * Utilities (logs)
