Re: Dataframe nested schema inference from Json without type conflicts

We could, but if a client sends some unexpected records in the schema (which happens more than I'd like, our schema seems to constantly evolve), its fantastic how Spark picks up on that data and includes it. Passing in a fixed schema loses that nice additional ability, though it's what we'll
