stack updated HBASE-3574:
-------------------------
Attachment: 3574.txt
This patch serializes HServerLoad into the regionserver ephemeral node instead
of passing the load over the heartbeat. It starts a Chore inside regionserver
to update the znode every 30 seconds.
I'm not going to finish this patch. To complete, I'd have to make investment
in translating znode content into HServerInfo, a class deprecated by patch over
in hbase-1502. Instead, I'm going to close this issue and roll it into
hbase-1502.

> The master ui and shell report on cluster load by reading the serverload
> delivered by each RS on heartbeat. HBASE-1502 is removing heartbeat. Need
> to do serverload otherwise. I'm thinking of writing it instead into the RS
> ephemeral node and having the master UI, etc. read it from zk instead.
