Andrew Purtell commented on HBASE-14703:
----------------------------------------
Yeah it gets confusing because we have RMs on minor 1.x branches now where in
the pre 1.0 days the RM is in charge of a major line (98, 94, etc). So I make
decisions where each 0.98.x release is a minor release, and RMs for 1.x
branches make decisions where each release there will only be a patch release.
We don't have a RM for branch-1. Maybe we should always have a RM in waiting
for that. Food for thought.

> We are trying to fix the stats implementation, by moving it out of the Result
> object and into an Rpc payload (but not the 'cell payload', just as part of
> the values returned from the request). This change will also us use easily
> switch to AsyncProcess as the executor, and support stats, for nearly all the
> rpc calls. However, that means when you upgrade the client or server, you
> will lose stats visibility until the other side is upgraded. We could keep
> around the Result based stats storage to accommodate the old api and send
> both stats back from the server (in each result and in the rpc payload).
> Note that we will still be wire compatible - protobufs mean we can just ride
> over the lack of information.
> The other tricky part of this is that Result has a
> non-InterfaceAudience.Private getStatistics() method (along with two
> InterfaceAudience.Private addResults and setStatistics methods), so we might
> need a release to deprecate the getStats() method before throwing it out?
