[GitHub] [hadoop-ozone] sodonnel opened a new pull request #1491: HDDS-4340. Add Operational State to the datanode list command

sodonnel opened a new pull request #1491:
URL: https://github.com/apache/hadoop-ozone/pull/1491


   ## What changes were proposed in this pull request?
   
   The existing CLI command `ozone admin datanode list` provides output like:
   
   ```
   bash-4.2$ ozone admin datanode list
   Datanode: f2b2452a-bf7b-4c6d-b2d6-a0d9d219b21a (/default-rack/172.20.0.8/ozone_datanode_1.ozone_default/2 pipelines)

   Datanode: 57c7fd5f-e32c-4de9-a04a-89d8d4273431 (/default-rack/172.20.0.6/ozone_datanode_3.ozone_default/2 pipelines) 
   Related pipelines:

   16561bc4-746a-4c79-b6f8-1c275b31e37d/THREE/RATIS/OPEN/Follower
   ```
   
   We should extend this to show the "Operational State" of the node for decommission, giving output like this:
   
   ```
   bash-4.2$ ozone admin datanode list
   Datanode: cbd31d42-dc9d-4561-a800-2178fdb45866 (/default-rack/172.21.0.6/ozone_datanode_3.ozone_default/2 pipelines)
   Operational State: IN_SERVICE
