an ugly set of hacks to accomplish this big picture goal
"While you're user=jenkins on a machine that's not in the hadoop cluster, submit a h2o on hadoop job to a hadoop cluster, and oh by the way, do it as another user, who has stronger permissions than you (0xcustomer) for access to datasets" and make sure you leave no mess on the hadoop cluster, if the job fails somehow.

And boil the ocean.
