             Summary: Avro union in cogroup doesn't check for nested unions
                 Key: CRUNCH-573
                 URL: https://issues.apache.org/jira/browse/CRUNCH-573
             Project: Crunch
          Issue Type: Bug
    Affects Versions: 0.13.0
            Reporter: Adric Eckstein


If one of the Cogroup.cogroup() inputs PType is an avro union, the cogroup() method attempts to construct a union of the input PTypes, which throws a Avro RuntimeException for a nested union.  This is similar to CRUNCH-547.

The bug could be fixed by either modifying the Avros.unionOf() method to check for union input types, or by unnesting the types in cogroup() prior to constructing the avro union.
