----------------------------------
Summary: Resolve using child metadata attributes as fallback
Key: SPARK-34547
URL: https://issues.apache.org/jira/browse/SPARK-34547
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.1.0
Reporter: Karen Feng
Today, child expressions may be resolved based on "real" or metadata output
attributes. If a "real" attribute and a metadata attribute have the same name,
we should prefer the real one during resolution. This resolution fails today,
although the user may not be aware of the metadata.
