Benjamin Reed commented on PIG-30:
----------------------------------

Excellent job Alan! That was a lot of work! Just a couple of small comments:

*  Do we need to expose DefaultDataBag, SortedDataBag, and DistinctDataBag? We don't want people constructing them directly right? Maybe we should make them package protected.

* One reason to expose SortedDataBag would be to get the sort spec. Do we want to expose that?

> We should never use DataBag directly; instead, we should always use BigDataBag. I think we already do this. The problem is that the logic in BigDataBag is hard to follow and it is made more complicated because it subclasses DataBag. We should merge these two classes together.
