Description
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.
