[jira] [Created] (HDFS-12333) Ozone: Extend Datanode web interface
with SCM information
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.
