[jira] [Created] (SPARK-34555) Resolve metadata output

Karen Feng created SPARK-34555:
----------------------------------

             Summary: Resolve metadata output
                 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


Today, we can't resolve a metadata column from a Spark SQL dataframe with `df.col("metadataColName")`. This is because metadata output is only used during `resolveChildren`; it should likely also be used by `resolve`.
