While ripping through the fluo code, I tried to make as members final as possible. A quick check of the accumulo code finds that we don't even make the log4j log entries consistent as "private static final". Some log members are non-private because components still use them even though they have been refactored into their own files. Some members are protected on purpose, and are meant to be re-used by subclasses (especially in tests).
To the extent possible, make the log4j log members consistent.
