Josh Wills commented on CRUNCH-280:
-----------------------------------
It might be possible, although I'm worried about the performance hit involved.
We could serialize the PTableType that was used for the shuffle and use it to
deserialize the data to use with the normal comparator. I think this is
something we do already in the Sort library for handling multi-reducer sorts,
so there might be some patterns we could reuse there.

> It seems that Sort#sort can only uses the default comparator. It would be
> nice to make it to be specified by clients.
