Zheng Hu commented on HBASE-20481:
----------------------------------
bq. so the current API is enough to tell the ReplicationEndpoint whether the
peer is serial or not...
OK, the setSerial() method can be removed now..
bq. You make everything serial, but actually, we only need the serial guarantee
inside a region, for different regions we can replicate them parallelly...
You are right, will update this patch..
> Add a setSerial method to ReplicationEndpoint

> When debugging HBASE-20475, [~openinx] found that the
> HBaseInterClusterReplicationEndpoint may send the entries for the same
> regions concurrently, which breaks the serial replication.
> As long as we can have multiple ReplicationEndpoint implementation, just fix
> HBaseInterClusterReplicationEndpoint is not enough, we need to add a
> setSerial method to ReplicationEndpoint, to tell the implementation that you
> should keep the order of the entries from the same region.
