Unfortunately the datanucleus-connectpool refuses to honor my request for
commons-pool 1.2 and instead fetches 1.3, which ,you guest it, does not work. I
am going to submit the original, figuring out what ivy is trying to do is
taking too long.

Personally, I agree that the cost/benefit of ivy is shaky, but if Hive as a
project has chosen it, then we should use it where possible. If that decision
needs to be revisited, then it would be good to resolve that.
