      Description

      Replicate join input that was broadcast to union vertex now needs to be broadcast to all the union predecessors. So we need to

      • Create edges from the Replicate join input to all the union predecessors
      • Change replicate join input to write to multiple outputs.

      This can be further optimized by using a shared edge which is yet to be implemented in Tez (TEZ-391)
