Allison Wang created SPARK-33697:
------------------------------------
Summary: UnionExec should always require column ordering in
RemoveRedundantProjects
Key: SPARK-33697
URL: https://issues.apache.org/jira/browse/SPARK-33697
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.1.0
Reporter: Allison Wang
UnionExec requires its children's columns to have the same order in order to
merge the columns. Currently, the physical rule `RemoveRedundantProjects` can
pass through the ordering requirements from its parent and incorrectly remove
the necessary project nodes below a union operation.
