> org.apache.spark.sql.catalyst.util.ResolveDefaultColumns#analyze method accepts 3 parameter
> 1) Field to analyze
> 2) Statement type - String
> 3) Metadata key - CURRENT_DEFAULT or EXISTS_DEFAULT
> Method org.apache.spark.sql.connector.catalog.CatalogV2Util#structFieldToV2Column
> pass fieldToAnalyze and EXISTS_DEFAULT as second parameter, so it is not metadata key, instead of that, it is statement type, so bad expression is analyzed.
