stack commented on HBASE-3647:
------------------------------
To be clear, for this patch to be committed, we will need to up our rpc version
on all proxy interfaces. HServerLoad is buried inside HServerInfo at the
moment. Its looking like pressure is building such that we will have to up our
version numbers -- hbase-1502 where we rejigger heartbeat includes deprecation
of HSA and redo of HSI -- but also Gary has patch to include cluster id in
ClusterStatue.... So, the RPC version bump looks like it'll happen soon.
We'll apply this patch then.

> Distinguishing read and write request counts, on top of HBASE-3507, would
> benefit load balancer.
> The action for balancing read vs. write load should be different. For read
> load, region movement should be low (to keep scanner happy). For write load,
> region movement is allowed.
> Now that we have cheap(er) counters, it should not be too burdensome keeping
> up the extra count.
