Duo Zhang commented on HBASE-20481:
-----------------------------------
OK, see the code.
BTW, you can implement a method called replicate, and move the code in
Replicated to this method. You can use lambda to convert the method to a
Callable, and in this way, in RegionSerialReplicator, you do not need to create
a Replicator and call its call method which looks a bit strange...
> 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.
