> In AMv2, if a RS is not aligned with Master notions of how the world is, then
> the Master will kill the deviant RS (TODO: is forcing compliance via less
> radical means -- but that is how it is currently).
> The shell currently allows by-passing the Master to make cluster
> modifications such as our being able to send a close directly to a
> RegionServer for it to execute locally. This facility was used in the past to
> do fix-up when Master lost account of Region locations. In the new regime,
> such mis-accounting should no longer happen and, should a user mistakenly do
> an explicit close against a RS, the consequences will be more than the user
> bargained for; the Master will shut down the RS as soon as it reports close
> of a Region the master thinks should be open (No independence allowed!).
> This issue is to review shell Region and Table manipulation commands to purge
> those that by-pass Master or at least to add big warning.
