-------------------------------------
Summary: Do not remove semijoin branch if it feeds to TS->DPP_EVENT
Key: HIVE-17399
URL: https://issues.apache.org/jira/browse/HIVE-17399
Project: Hive
Issue Type: Bug
Reporter: Deepak Jaiswal
Assignee: Deepak Jaiswal
If there is an incoming semijoin branch to a TS which has DPP event, then try
to keep it as it may serve as an excellent filter for DPP thus reducing the
input to join drastically.
