Duo Zhang commented on HBASE-20425:
-----------------------------------
There is another possible way to address this is to remove the last (or first?)
clusterIds when replaying the remote WAL. You can have a try to see which one
is better. Maybe the latter one is easier...
> Do not write the cluster id of the current active cluster when writing remote
> WAL

> The wal entries which are replayed when converting a cluster from S to DA
> need to be replicated back to the old A cluster. if we write the cluster id
> of A into the wal entries, we will skip replicating them...
