             Summary: Union of two PTable causes NPE in MSCRPlanner
                 Key: CRUNCH-154
                 URL: https://issues.apache.org/jira/browse/CRUNCH-154
             Project: Crunch
          Issue Type: Bug
    Affects Versions: 0.4.0
            Reporter: Tim van Heugten
            Priority: Critical
         Attachments: FirstLetterKeyFn.java, MSCRPlannerNpeTest.java

Two PTables are created from two PCollections. 
One of the PCollections is materialized.
The PTables are unioned and materialized.
When pipeline.run() is called a NPE is thrown in MSCRPlanner.

Note that I use materialize while any output target would have the same effect.
