Subject [jira] [Created] (CRUNCH-278) Improvements to MapsideJoin code

Josh Wills created CRUNCH-278:

             Summary: Improvements to MapsideJoin code
                 Key: CRUNCH-278
             Project: Crunch
          Issue Type: Bug
          Components: Core, MapReduce Patterns
            Reporter: Josh Wills
            Assignee: Josh Wills

The fact that we have special-case code in the MapsideJoinStrategy for the in-memory and MR-based
Pipeline instances has always bugged me, so I set out to eliminate the distinction between
the two impls by creating a new interface, ReadableSourceBundle<T>, that encapsulates
the MR and in-memory specific logic for doing mapside joins in order to remove the special-case
code in MapsideJoinStrategy and hopefully make other implementations that use our mapside-join
patterns much easier to test.
