Sure on bump the version number. Pretty soon they'll be ignored so no harm
using up a few. Good stuff G.
Cool, I'll bump the version number for now.
I believe I've answered all your questions below. Let me know if I missed
anything.
Thanks for the review.

Thanks, will do.

Good point, I can catch at a higher level.

Will do.

No, the rest of the functions in HMasterInterface need to be converted. This
is the region-level stuff, I still have column-level, table-level and
miscellaneous stuff to do. I've filed a JIRA for the column-level stuff; I'll
file JIRAs for the others once I figure out how I'm going to break down the
work.

ServiceException is coming from pb, that's right. So when we either get rid of
HMasterInterface or repurpose it, the interface will define that we throw
ServiceExceptions.

I'm not sure what you mean by "having to hoist all these pb classes up in here
AND into HMasterInterface." -- this is HMasterInterface?
Also, I don't think PB will be nice and generated usable javadoc for you, so
I'm not sure how to provide javadoc comments without redeclaring the functions?
I admit to being completely ignorant about this area.
Once everything in HMasterInterface is converted to use PB, we can either
declare a new class for the representation (similar to
RegionServerStatusProtocol) or just re-purpose HMasterInterface for that. What
is your preference?

bq. Summary
bq. -------
bq.
bq. Converted all the region-level calls in HMasterInterface to use Protobufs
(move, assign, unassign).
bq.
bq. I've put the new generated calls in HMasterInterface rather than a new
class, because it is easier to have one class for now, until I convert
everything. This will only be temporary, but let me know how you want to
handle. Bump the version number?
