Subject Reworking the use of log levels
Date Sat, 25 Oct 2014 05:14:18 GMT

Right now we have many failure paths where we send stack traces to log
files at ERROR / WARN. In an effort to make things easier to operate, I'd
like to propose we move towards:

* INFO/WARN/ERROR : description of failure and if possible an action an
operator could take to fix/diagnose
* DEBUG : information needed to handle failures that require developer
action, i.e. stack traces

I figure this can go as one or more subtasks off of HBASE-12341, but wanted
to float things here before I get started.
