------------------------------------
I'm working on this.
> 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
> Priority: Major
>
> 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.
