> Key: SPARK-28359
> URL: https://issues.apache.org/jira/browse/SPARK-28359
> Project: Spark
> Issue Type: Bug
> Components: PySpark, SQL
> Affects Versions: 3.0.0
> Reporter: Hyukjin Kwon

> Current UDFs available in `IntegratedUDFTestUtils` are not exactly no-op. It
> converts input column to strings and outputs to strings.
> This causes many issues, for instance,
> https://github.com/apache/spark/pull/25128 or
> https://github.com/apache/spark/pull/25110
> Ideally we should make this UDF virtually noop.
