Riley Patterson commented on HBASE-4057:
----------------------------------------
Also @Andrew, currently, the only user-facing exposure is through jamon.
However, the TaskMonitor's getTasks() method is a very straightforward internal
exposure mechanism, and it would be relatively trivial to expose show
processlist to the shell or any other user interface.
My internship ends on Friday (tomorrow), so I don't have time to do this while
I'm at Facebook, but if you think shell exposure is important, I can implement
it independently after my internship ends without too much trouble. However, I
would really like to get this core functionality in before I leave Facebook.

> One of the features that our DBAs use for MySQL analysis is "show
> processlist", which gives application-level stats about the RPC threads.
> Right now, we use jstack but that is very core-developer-centric. We need to
> create a similar tool that DBA/Ops/AppDevs can use.
