---------------------------------------
Summary: Add additional test coverage for input_file_name_expr
Key: SPARK-45772
URL: https://issues.apache.org/jira/browse/SPARK-45772
Project: Spark
Issue Type: Task
Components: PySpark
Affects Versions: 4.0.0
Reporter: Utkarsh Agarwal
https://issues.apache.org/jira/browse/SPARK-44705 introduced changes to the
evaluation of the `input_file_name()` expression in the presence of Python
UDFs. This was done to maintain the behavior of the `input_file_name()`
expression when the execution model of the PythonRunner was made
single-threaded by https://issues.apache.org/jira/browse/SPARK-44705. We should
add additional test coverage for `input_file_name()` + Python UDFs to prevent
future breakages.
