[jira] [Updated] (PIG-3766) Use ONE_TO_ONE edge and IdentityInOut in skewed join intermediate vertex

["Rohini Palaniswamy (JIRA)" <ji...@apache.org>]

Rohini Palaniswamy updated PIG-3766:
------------------------------------

    Attachment: PIG-3766-1.patch

Changes done:
  1) Removed the POLocalRearrange in SampleVertex and replaced it with a POValueOutTez for both orderby and skewedjoin. POValueOutTez takes multiple outputs. So got rid of the POSplit as well in skewed join sample vertex.
  2) Replaced the POPackage+POLocalRearrange in the partition vertex of left table (vertex 3) with a POIdentityInOutTez moving the project in POLocalRearrange into the POLocalRearrange in vertex 1. Also made the edge 1-1 between vertex 1 and vertex 3.

> 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.
