Thank you for the suggestions.
Writing a custom LoadFunc seems like a valid solution for me, given that I don't currently have Hive or HCatalog installed and I'm working on more of an ad-hoc problem at this point.
HCatalog seems like a good solution for doing this type of thing on a repeated basis and with many data sets. I will read up on it for sure.
