                 Key: HDDS-11032
                 URL: https://issues.apache.org/jira/browse/HDDS-11032
             Project: Apache Ozone
          Issue Type: Bug
          Components: Ozone Recon

Ozone Recon - Decommissioned datanodes shows up again after removing in Recon 
Datanodes page-

As part of HDDS-10409

Recon was allowing to remove the Decommissioned datanodes and was removing from 
Recon rocksDB nodes table, however Decommissioned datanodes continue to send 
heartbeats till they are being shutdown, so they get registered and added again 
in Recon memory map which makes them show up again in datanodes UI.

 

Solution is to allow only DEAD datanodes to be removed and skip other node 
status or node operational status datanodes.
