--------------------------------------
hey patrick. i was looking into modifying the sorting code so far, but you
are saying modify partitioning instead. great. will look into that approach
as well. it might be easier/cleaner.

> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 1.1.0

> Now that spark has a sort based shuffle, can we expect a secondary sort soon?
> There are some use cases where getting a sorted iterator of values per key is
> helpful.
