> 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.
