Review Comment:
The reason we need to register only in exception cases is that the cleanup
of files and directory under file upload path should happen on client side only
if job submission fails. If we register early, and job is submitted with
spark.kubernetes.submission.waitAppCompletion conf value as false, shutdown
hook will be called as soon as app submission completes and the files will be
deleted. This will case the job to fail as driver will not be able to find
these files.
