Vinayakumar B commented on HDFS-10440:
--------------------------------------
1. I didn't mean to change existing {{DataNode#getNamenodeAddresses()}} output.
It breaks the compatibility. So let it be just hostname. After this,
{{BPSA#getNameNodeAddress()}} could be private.
{code} for (BPServiceActor actor : bpos.getBPServiceActors()) {
- info.put(actor.getNNSocketAddress().getHostName(),
+ info.put(actor.getNameNodeAddress(),
bpos.getBlockPoolId());{code}
2. I am not very sure about giving link to {{/conf}} is good idea here since
other pages dont have this yet. May be this could be taken as a separate
improvement, together for all HTML pages.
{code}<li><a href="conf">Configuration</a></li>{code}
Other changes are looks good. Thanks for updates.
+1, once these are addressed.
FYI, You dont need to change the Jira status to "In-Progress" and back to
"Patch Available" every time.
Jenkins will pick up directly once the latest patch file is updated.

> 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)
