in orderby intermediate vertex
Rohini Palaniswamy created PIG-3732:
---------------------------------------
Summary: Use ONE_TO_ONE edge and IdentityInOut in orderby intermediate vertex
Key: PIG-3732
URL: https://issues.apache.org/jira/browse/PIG-3732
Project: Pig
Issue Type: Sub-task
Reporter: Rohini Palaniswamy
Assignee: Rohini Palaniswamy
Fix For: tez-branch
From the first vertex to the intermediate vertex that does the partitioning of the keys based on the WeightedRangePartitioner, 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.
