Yong Zhang commented on HBASE-15318:

Hi [~stack], thanks for your comment.
I read the design doc of HBASE-14350 and it subtask, but not find any thing about the region
server state management.  HBASE-14350 is more about region assignment manager.

> Current region server state is managed via znode created by region server, master just
listen these nodes. but we find many user network issue is not network disconnected but package
lost, which is hard to capture because connection between region server and zk is fine.
> This jira goal is region server state is managed by master without shared info in zk,
via enhancement heartbeat from region server to master.
