> So, cachearchive like class.zip or class.tar.gz were never set as part of the
> classpath even though they were properly set by DistributedCache.addArchiveToClassPath.
> It looks like we are parsing the classpath out of the configs, but then throwing that away.  It looks simple enough to add them in the correct place.
