Sangjin Lee commented on MAPREDUCE-6293:
----------------------------------------
Kicking off the jenkins build one more time. I suspect these test failures are
spurious, as there are no failures related with classloading issues (they're
mostly timeouts and other varierty). The patch is a no-op if the job
classloader is not set.
> uberized job fails with the job classloader enabled
