            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.
