[jira] [Created] (HBASE-28503) Keep entries in draining ZNode when HMaster is configured to reject decommissioned hosts

             Summary: Keep entries in draining ZNode when HMaster is configured to reject decommissioned hosts
                 Key: HBASE-28503
                 URL: https://issues.apache.org/jira/browse/HBASE-28503
             Project: HBase
          Issue Type: Bug
            Reporter: Ahmad Alhour


Last month we shipped a config feature to allow the HMaster to reject decommissioned hosts. After some testing internally at HubSpot, we discovered that the HMaster loses the entry of a decommissioned host from the draining ZNode when the RegionServer restarts or becomes dead.

Our proposal for this fix would be to keep entries in the draining ZNode as long as the HMaster is configured to reject decommissioned hosts.
