Rohini Palaniswamy created PIG-3766:
---------------------------------------

             Summary: Use ONE_TO_ONE edge and IdentityInOut in skewed join intermediate vertex
                 Key: PIG-3766
                 URL: https://issues.apache.org/jira/browse/PIG-3766
             Project: Pig
          Issue Type: Sub-task
            Reporter: Rohini Palaniswamy
            Assignee: Rohini Palaniswamy
             Fix For: tez-branch


>From the first vertex (left table load) to the intermediate vertex that does the partitioning of the keys based on the SkewedPartitionerTez, use ONE_TO_ONE Tez edge and unsorted output and input instead of using a shuffle edge. Also replace the POPackage->POForEach->POLocalRearrange in intermediate vertex with POIdentityInOutTez.
