             Summary: Analyze 'exists' default expression instead of 'current' default expression in structField to v2 column conversion
                 Key: SPARK-48286
                 URL: https://issues.apache.org/jira/browse/SPARK-48286
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 4.0.0
            Reporter: Uros Stankovic
             Fix For: 4.0.0


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.
