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.
