LGTM. Per @marmbrus's comment over on the JIRA, I don't think that the Hive assertion failures should necessarily block enabling this for the rest of Spark, so I'm going to merge this into master and all of the maintenance branches. Thanks for fixing this!

[JoshRosen]

Alright, picked this into master, branch-1.2, and branch-1.1. There's a nasty merge conflict when trying to pick this back into branch-1.0, so I'm going to not pick that for now and tag this for a possible backport in JIRA.
