Jonathan Gray commented on HBASE-1502:
--------------------------------------
Only did cursory look at patch, but looks like this still has it so startup is
via RPC but shutdown (will eventually be) via ZK... What exactly will be
transmitted each way in that startup RPC? Is it necessary?
Also, how does master get server load info now?

> HBase currently uses heartbeats between region servers and the master,
> piggybacking information on them when it can. This issue is to investigate if
> we can get rid of the need for those using ZooKeeper events.
