             Summary: Implement replicated join in Tez
                 Key: PIG-3604
                 URL: https://issues.apache.org/jira/browse/PIG-3604
             Project: Pig
          Issue Type: Sub-task
          Components: tez
    Affects Versions: tez-branch
            Reporter: Cheolsoo Park
            Assignee: Cheolsoo Park
             Fix For: tez-branch


I propose we implement replicated join as follows-
* Vertex 1: Loads replicated table and broadcasts it to vertex 2.
* Vertex 2: Loads fragmented table and join it with broadcasted input from vertex 1.
* New POPackage for vertex 2 that can consume a broadcast input and a file input needs to be implemented.
