Misty Stanley-Jones commented on HBASE-12396:
---------------------------------------------

I was thinking of taking this, but I think at least the first draft needs to be done by developers.

> Right now we don't provide any guidance on appropriate use of log levels, which leads to inconsistent use and in some cases exacerbating problems for tests and troubleshooting (see HBASE-12395). We should add a section on suggested use of log levels to the guide.
