> ----------------------------------------------------------------------------------------
>
> Key: HBASE-28503
> URL: https://issues.apache.org/jira/browse/HBASE-28503
> Project: HBase
> Issue Type: Bug
> Reporter: Ahmad Alhour
> Assignee: Ahmad Alhour
> Priority: Major
>
> Last month we shipped a config feature to allow the HMaster to reject
> decommissioned hosts (see:
> [HBASE-28342|https://issues.apache.org/jira/browse/HBASE-28342]). 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.
