> Remove dead and broken AutoSerializer class
> -------------------------------------------
>
> Key: SPARK-58991
> URL: https://issues.apache.org/jira/browse/SPARK-58991
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 4.2.0
> Reporter: Yicong Huang
> Priority: Major
> Labels: pull-request-available
>
> The `AutoSerializer` class in `python/pyspark/serializers.py` is dead and
> broken code and should be removed.
> * It is not exported in `__all__` and has no production callers.
> * Its `loads()` is broken under Python 3: it reads `_type = obj[0]`, which
> yields an `int` rather than a `bytes` value like `b"M"`/`b"P"`, so the type
> check never matches and every call raises `ValueError`.
> * The only reference is a smoke test in
> `python/pyspark/tests/test_serializers.py` (an import plus a `hash()` call).
> Proposed: delete the class and its two test references.
