> I was working on adding support for Parquet to Crunch, and ran into the issue
> that Parquet always assumes that the value it returns is on the "value" side
> of the key-value pair of an InputFormat/OutputFormat. Crunch, for
> semi-sensible historical reasons, makes this position dependent on the
> PTypeFamily (Avro PTypes write to the key, Writable PTypes write to the
> value). Since the Parquet InputFormat/OutputFormat treat the two types the
> same way, we need a way for the Source and Target implementations to override
> the default configuration of the PTypes and choose the right side for the
> given format.
