------------------------------------
bq. I believe meta is co-located with master (as per HBASE-10569)
Boom. This is the hunch I had, but I had no idea where to start looking to
verify. Thanks!
bq. this call should be going thru short-circuit connection and not RPC
layer..Let me take a look.
Absolutely. We shouldn't be making a separate RPC for this. MetaTableAccessor
could hopefully shortcircuit out if we're running inside the Master (although
I'm not directly sure how we would determine this).

> HBASE-12071, among other things, introduced annotating RPC methods to give
> certain methods priority over others. Namely, this helps ensure that client
> requests cannot starve out internal RPC between master and regionserver.
> Similarly, we can do the same thing for Master RPC methods that are invoked
> by RS's.
