> Key: HDDS-6894
> URL: https://issues.apache.org/jira/browse/HDDS-6894
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Stephen O'Donnell
> Assignee: Uma Maheswara Rao G
> Priority: Major
>
> Given a container which was queued as under replicated, check the container is still under-replicated, and if so figure out the new DN targets and create a command which can be schedule on a datanode to repair it.
> For EC, this may need to handle two types of under-replication - one caused by decommission where the replica just needs copied from the decommissioning host. The other where the replica needs to be reconstructed.
> If it makes sense these could be two separate classes.
