-----------------------------------

             Summary: MemPipeline.collectionOf() leads to NPE in PCollection.length()
                 Key: CRUNCH-468
                 URL: https://issues.apache.org/jira/browse/CRUNCH-468
             Project: Crunch
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.10.0
            Reporter: Jeremy Beard
            Assignee: Josh Wills


MemPipeline.collectionOf() creates a PCollection with a null PTypeFamily. When PCollection.length()
is run it uses the PTypeFamily of the PCollection to serialize the running count of the records,
which leads to a NPE for PCollections created as above.
