> Key: HDDS-8172
> URL: https://issues.apache.org/jira/browse/HDDS-8172
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: SCM
> Reporter: Arun Sarin
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.4.0
>
>
> For an EC container which has 2 replicas for the same index, with one
> decommissioning and one in_maintenance, the decommission logic in
> ECUnderReplicationHandler can send a command for the replica, and then the
> maintenance logic can send another replication command for the same container
> to a different target. If they both succeed it will likely result in over
> replication.
> To solve this, we probably need to adjust the pending ops between each stage
> of the processing, so as then the maintenance logic would be "fixed by
> pending" and avoid sending the second command.
