Nick Dimiduk commented on HBASE-8158:
-------------------------------------
JarFinder will build a jar from class files if a packages jar cannot be
located. I believe the preference is to use an existing packaged jar over
bundling one for the run. Hence, actually invoking it should be a last resort.
This was *not* the behavior before I touched this bit of code ;)
