   @Apache9 Thank you for reviewing.
   
   > What does the owner mean here? I think we have the region server name in the queue name on zk?
   
   The owner is the region server holding replication queue. And yes, the region server name is included in zk path. But replication server is first to get region server holding queue and queueid, and then use them to form the zk path of queue. 
   
   For compatibility, replication server does not actually move the queue to its own zk directory, so replication server needs to know which zk directory of regionserver the queues that it consumes are in.
   
   On the regionserver, the holder and consumer of the queue are its own, so there is no need to record the owner extra, which is different for the replication server.
