---------------------------------------
Assignee: Stephen O'Donnell (was: Siddhant Sangwan)
> Incorrect sorting order for all unhealthy replicas in
> RatisOverReplicationHandler
> ---------------------------------------------------------------------------------
>
> Key: HDDS-9747
> URL: https://issues.apache.org/jira/browse/HDDS-9747
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: SCM
> Reporter: Siddhant Sangwan
> Assignee: Stephen O'Donnell
> Priority: Major
>
> {code}
> if (allUnhealthy) {
> // prefer deleting replicas with lower sequence IDs
> return replicas.stream()
> .sorted(Comparator.comparingLong(ContainerReplica::getSequenceId)
> .reversed())
> .collect(Collectors.toList());
> }
> {code}
> This should actually be the opposite, allowing lower sequence IDs to be
> deleted first. Also need to consider what happens when two replicas have the
> same sequence ID - how are ties broken? Consistent ordering matters in case
> of SCM failover.
