Heng Chen commented on HBASE-13773:
-----------------------------------

If zk removed, how the slaves get notified by master if there are some new wals to replicate?
Polling by slave?

Sorry, i got it now.  master do polling and push wals to slave.

I make a ReplicationQueues implementation with system table,  and upload it.  Any suggestions?
