Duo Zhang commented on HBASE-25664:
-----------------------------------
This may cause trouble for the RemovePeerProcedure?
Anyway, what is the actual problem here? It is still being deleted in
background? Or there are some bugs which leave the queues there for ver?
> Adding replication peer should handle the undeleted queue exception

> Currently, if we try to add a peer and there is a replication queue existing
> for that peer, it doesn't let the replication peer created.
> Instead, we should delete the queue and proceed with the creating of
> replication peer. Any queue without no corresponding replication peer is
> useless anyway. So, we shouldn't wait for cleaner to come and clean it before
> creating the peer.
