Custom Partitioner
------------------

                 Key: PIG-282
                 URL: https://issues.apache.org/jira/browse/PIG-282
             Project: Pig
          Issue Type: New Feature
            Reporter: Amir Youssefi
            Priority: Minor


By adding custom partitioner we can give control over which output partition a key (/value) goes to. We can add keywords to language e.g. 

PARTITION BY UDF(...)

or a similar syntax. UDF returns a number between 0 and n-1 where n is number of output partitions.
