Josh Wills created CRUNCH-412:

             Summary: MemPipeline mode for simulating MapReduce quirks
                 Key: CRUNCH-412
             Project: Crunch
          Issue Type: Improvement
          Components: Core
            Reporter: Josh Wills
            Assignee: Josh Wills

>From a discussion on the mailing list, we'd like to have a MemPipeline mode that simulates
a couple of the quirks of MapReduce/MRPipeline for more reliable testing, namely:

1) Shuffle code that re-uses reduce-side objects so we can detect bugs caused by object modification,
2) Serializes/deserializes DoFns before running them in order to test for any non-serializable
code that sneaks into a pipeline.
