stack updated HBASE-1502:
-------------------------
Attachment: 1502.txt
Here is a start -- the fun part. Removed HMsg and then redid the
HMasterRegionInterface to remove the heartbeating. Was able to remove a bunch
of other crud from Master and Regionserver. TODO: Splits, shutdown, and load.
The report into the master by RS remains. It'll be passed back the hostname to
use. It'll add this up into its znode (it'll only add znode after it has
registered w/ Master). The znode will then be updated by the RS on a period
with its load info. Master loadbalancer will read it from there. Regards
Splits, after talking w/ Jon, its a new RIT state. Shutdown, I'll have think
about it and write something up.

> 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.
