Hyukjin Kwon created SPARK-61204:
------------------------------------
Summary: Give None for the className of a builtin function without
a class in Catalog.listFunctions and getFunction, as PySpark does
Key: SPARK-61204
URL: https://issues.apache.org/jira/browse/SPARK-61204
Project: Spark
Issue Type: Bug
Components: Connect
Affects Versions: connect-rust-4.3.0
Reporter: Hyukjin Kwon
The server sends a null className for the builtins `!=`, `<>`, `case` and `||`.
The Rust catalog reads a null string column as "", so the Python
Function.className is "" where PySpark gives None.
Repro: `[f.name for f in spark.catalog.listFunctions() if f.className is None]`
is empty in the drop-in and holds the four names in PySpark 4.3.0.
The fix makes Function.class_name an optional string through the core and the
Python NamedTuple.
