Vinayakumar B commented on HDFS-10440:
--------------------------------------
I was having some problem to connect to DataNode's HTTP port in my eclipse run
in windows. Seems to be problem with PortUnificationHandler. I was able to
connect to proxy port. Anyway this comes without patch also. That I will dig
more and raise a Jira.
About patch, some comments.
1. Header {{DataNode on 127.0.0.1:54107}} should contain 'Data port' not 'http
port' as Data Port is used as the ID of the datanode everywhere.
2. {{Namenode Address}} should contain port as well. Not just hostname. Its
'Namenode Address' not just 'NameNode Host'. Though earlier JMX was returning
only Hostname, now its time to be right in new JMX api.

> 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)
