> Resolve metadata output from DataFrame
> --------------------------------------

> Key: SPARK-34555
> URL: https://issues.apache.org/jira/browse/SPARK-34555
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Karen Feng
> Assignee: Karen Feng
> Priority: Minor
> Fix For: 3.2.0, 3.1.2
>
>
> Today, we can't resolve a metadata column from a Spark dataframe from Scala
> with {{df.col("metadataColName")}}. This is because metadata output is only
> used during {{resolveChildren}} (used during SQL resolution); it should
> likely also be used by {{resolve}} (used during Scala resolution).
