First release will enable this config property in whole cluster, hmaster and region server. In the second release, we will need to enable ReplicationMarkerChore which will create the special marker rows. There will be a problem if `hbase.regionserver.replication.sink.tracker.enabled` is enabled on regionserver and disabled on hmaster and ReplicationMarkerChore is enabled. -- This is an automated message from the Apache Git Service.
