--------------------------
Summary: Find out whether it's possible to remove UnionOperator
from original operator tree [Spark Branch]
Key: HIVE-8024
URL: https://issues.apache.org/jira/browse/HIVE-8024
Project: Hive
Issue Type: Task
Components: Spark
Reporter: Chao
Assignee: Chao
Currently, after operator tree is processed, the generated works with union
operators will go through {{GenSparkUtils::removeUnionOperators}}, which will
clone the original operator plan associated with the work, and remove union
operators in it. This caused some issues as seen, for example, in HIVE-7870.
This JIRA is created to find out whether it's possible to just remove the union
operators in the original plan.
