Subject [jira] [Created] (CRUNCH-22) Join functions break when non-mapped types are used as a join key
Date Sat, 21 Jul 2012 10:50:33 GMT
Gabriel Reid created CRUNCH-22:
----------------------------------

             Summary: Join functions break when non-mapped types are used as a join key
                 Key: CRUNCH-22
                 URL: https://issues.apache.org/jira/browse/CRUNCH-22
             Project: Crunch
          Issue Type: Bug
            Reporter: Gabriel Reid
         Attachments: CRUNCH-22.patch

When non-mapped types (i.e. custom Writables or Avro records) are used as a join key in all
join functions, the join does not operate correctly (and becomes closer to producing a Cartesian
product) due to object re-use in Hadoop.
