> Remove unnecessary type: ignore comments in pyspark.sql.udf and group
> ---------------------------------------------------------------------

> Key: SPARK-58312
> URL: https://issues.apache.org/jira/browse/SPARK-58312
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 4.3.0
> Reporter: Haotian Sun
> Priority: Minor
> Labels: pull-request-available
>
> Several # type: ignore comments in python/pyspark/sql/udf.py and
> python/pyspark/sql/group.py can be removed by fixing the underlying type
> issues:
> * In UDFRegistration.register, a UDF is built and wrapped by _create_udf,
> then immediately unwrapped via the ._unwrapped attribute. Building the
> UserDefinedFunction directly removes this round-trip and 2 [attr-defined]
> ignores.
> * In group.py, the @dfapi/@df_varargs_api decorated methods intentionally
> have docstring-only bodies and trigger 6 [empty-body] ignores. These are
> replaced by a single file-level disable-error-code directive, matching the
> style already used in dataframe.py, column.py, window.py, and table_arg.py.
