Nick Dimiduk reopened HBASE-24309:
----------------------------------

Looks like this one is cause of a new compiler warning. Reopening for addendum.

> In general, a library should not force the down stream users to use a 
> specific logging framework, and this is why there is a slf4j library.
> For HBase, since we also publish the testing-util module which almost depends 
> on all other sub modules, we should not introduce logging dependencies other 
> than slf4j-api in these modules. We should only add log4j dependencies in 
> hbase-assembly and ship it with our binary distribution.
> This is also important for switching to log4j2.
