Subject [jira] [Created] (HDFS-12333) Ozone: Extend Datanode web interface with SCM information
Date Mon, 21 Aug 2017 16:02:00 GMT
Elek, Marton created HDFS-12333:
-----------------------------------

             Summary: Ozone: Extend Datanode web interface with SCM information
                 Key: HDFS-12333
                 URL: https://issues.apache.org/jira/browse/HDFS-12333
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: HDFS-7240
    Affects Versions: HDFS-7240
            Reporter: Elek, Marton
            Assignee: Elek, Marton


Current Datanode web interface shows information about the Block Pools:

* Namenode Address
* BlockPoolID
* ActorState
* Last Heartbeat
* Last Block Report

I propose in this jira to add the same information about the SCM (if the datanode is a member
of ozone cluster). It would help to check the current state of the datanode (is ozone enabled?
Is there an active connection to the SCM?)

Suggested information to display:
* SCM hostname/address
* EndpointState (GETVERSION, REGISTER, HEARTBEAT, SHUTDOWN)
* version (from the VersoinResponse)
* missedCount

They could be displayed with publishing JMX information from SCMConnectionManager or EndpointStateMachines.

Possible report of Last Heartbeat/Container report should be investigated.
