Duo Zhang commented on HBASE-19635:
-----------------------------------

I do not think a timer is suitable here, the should complete the procedure 
ASAP. Maybe we can put it into the heartbeat thread but the logic may be 
complicated.

A whole thread is the easiest way for now and it will not cost too much. And 
since later other operations such as ACL change, snapshot will also use this 
framework, I think an extra thread is worth? And we can still merge it into the 
heartbeat thread in the future.

Thanks.
