Stephen O'Donnell commented on HDDS-7582:
-----------------------------------------
It would make sense to add them to the excluded list. I think it is a bug for
them not to be added as it could result an attempt to put two replicas on the
same DN.
> ECUnderReplicationHandler does not consider pending adds when finding targets

> ECUnderReplicationHandler finds new target datanodes where replicas of an
> under replicated container can be added. However, it does not exclude
> datanodes that are pending addition of a replica of that container from the
> list of targets. Ideally, if we've already queued a command to add a replica
> to a DN, we shouldn't add another command.
> This Jira investigates why datanodes pending adds aren't excluded. Is there a
> reason or is this a bug?
