Weiwei Yang commented on HDFS-10440:
------------------------------------
Patch updates:
* Added ReservedSpaceForReplicas and NumBlocks in Volume Information section
* Added per-BP-actor state in Block Pools section
* Minor modification to DataNodeMXBean.getNamenodeAddresses to include actor
states
* Added error handling when it's unable to retrieve info from JMX call
New screen shots attached, they are taken from latest trunk build, I setup 2
NNs and the datanode UI looks like [#datanode_2nns.html.002.jpg], when it fails
to load info from datanode JMX, it shows like [#datanode_loading_err.002.jpg].
And by clicking Utilities, it shows the link to view configurations and logs
[#datanode_utilities.002.jpg].
Please kindly review and comment, thank you.
