Subject [jira] [Commented] (HDFS-10440) Improve DataNode web UI
Date Fri, 24 Jun 2016 15:16:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15348411#comment-15348411

Weiwei Yang commented on HDFS-10440:

Hello [~vinayrpet]

Thank you for the input.I thought IPC port would be useful because there are quite some dfsadmin
command utilities using {{datanode_host:ipc_port}} as an identifier. But I also agree with
you,  because I noticed the *Node* entry on Namenode UI -> Datanodes lists datanode with
its data port, so it's more consistent. I just uploaded v7 patch for this.

> 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)
