Yicong-Huang opened a new pull request, #57433: URL: https://github.com/apache/spark/pull/57433
### What changes were proposed in this pull request? Remove the `ArrowStreamPandasUDFSerializer` class from `python/pyspark/sql/pandas/serializers.py`. ### Why are the changes needed? All non-grouped Pandas eval types (`SQL_SCALAR_PANDAS_UDF`, `SQL_SCALAR_PANDAS_ITER_UDF`, `SQL_MAP_PANDAS_ITER_UDF`) were refactored to use `ArrowStreamSerializer` with `ArrowBatchTransformer`, and the last remaining subclass `ApplyInPandasWithStateSerializer` was removed in SPARK-58243. The class no longer has any instantiation sites, so it can be removed. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing tests. No behavior change. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
