> A lot of troubleshooting involves answering the question "well, what is your
> server doing right now?" Today, that involves some combination of
> interpreting jstack output and/or trudging through logs. Problems with these
> methods are: (a) users may not have direct ssh access to regionserver
> machines in production environments, (b) logs are very verbose, so hard to
> separate what's still going on vs stuff that might have completed, and (c)
> interpreting jstack requires a pretty good knowledge of the codebase plus
> diving into source code.
> I'd like to add a singleton (for now) which takes care of tracking any major
> actions going on in the region server and master.
