> 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.
