Jesse Yates commented on HBASE-14703:
-------------------------------------
I committed to master and will work on a version for branch-2.
I'm tentative to move this any further back due to the recent discussion on the
dev list on what should and shouldn't be moved back. Its a nice improvement,
but does introduce some changes to the AsyncProcess. I'll leave it up the RMs
if they want it (but I'll do my best to do the work, if they want it
backported). thoughts [~apurtell] [~ndimiduk] [~mantonov] [~busbey]?

> 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?
