------------------------------------
Target Version/s: 1.4.2
> RM selects replicas to delete non-deterministically if nodes are overloaded
> ---------------------------------------------------------------------------
>
> Key: HDDS-12115
> URL: https://issues.apache.org/jira/browse/HDDS-12115
> Project: Apache Ozone
> Issue Type: Bug
> Components: SCM
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.0.0
>
>
> When RM selects nodes to delete replicas from, it sorts the replicas by
> datanode UUID and then iterates the list. If a node is overloaded when it is
> selected for delete, then rather than holding that delete for later, it skips
> it and tries the next replica in the list. This can result in
> non-deterministic delete selection, which we want to avoid.
