    Description

      NN UI is not showing which DN is "Decommissioned "and "Decommissioned & dead"

      Root Cause –
      "Decommissioned" and "Decommissioned & dead" icon not reflected on NN UI

      When DN is in Decommissioned status or in "Decommissioned & dead" status, same status is not reflected on NN UI

      DN status is as below –

      hdfs dfsadmin -report

      Name: 10.xx.xx.xx1:50076 (host-xx1)
      Hostname: host-xx
      Decommission Status : Decommissioned
      Configured Capacity: 230501634048 (214.67 GB)
      DFS Used: 36864 (36 KB)

      Dead datanodes (1):
      Name: 10.xx.xx.xx2:50076 (host-xx2)
      Hostname: host-xx
      Decommission Status : Decommissioned

      Same is not reflected on NN UI.

      Attached NN UI snapshots for the same.
