Subject [jira] Created: (PIG-963) Join in local mode matches null keys
Date Wed, 16 Sep 2009 01:35:57 GMT
Join in local mode matches null keys
------------------------------------

                 Key: PIG-963
                 URL: https://issues.apache.org/jira/browse/PIG-963
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.4.0
            Reporter: Pradeep Kamath
            Assignee: Pradeep Kamath


Semantics of join and cogroup dictate that null values for the keys from different inputs
are NOT supposed to match. This is true in map reduce mode but local mode incorrectly matches
these records.
