[jira] [Created] (HBASE-28342) Decommissioned hosts should be rejected by the HMaster
Ahmad Alhour created HBASE-28342: Summary: Decommissioned hosts should be rejected by the HMaster Key: HBASE-28342 URL: https://issues.apache.org/jira/browse/HBASE-28342 Project: HBase Issue Type: Bug Reporter: Ahmad Alhour We had an issue with a cluster, internally at HubSpot, where a decommissioned RegionServer was still being picked up by the HMaster. The host the RegionServer was living on was impaired, and we couldn't correctly kill the RegionServer, so the HMaster would periodically hear back from the host and remove it from its dead host's list. We would like to implement a fix so that this doesn't happen. We're thinking of adding a boolean flag to the Decommission RegionServer Admin API that signifies ignoring the startcode of the servername, when the boolean is True the host will be rejected every time it comes back even if it had a different startcode. -- This message was sent by Atlassian Jira (v8.20.10#820010)
[jira] [Created] (HBASE-28503) Keep entries in draining ZNode when HMaster is configured to reject decommissioned hosts
Ahmad Alhour created HBASE-28503: 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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
