> Unify verify_result and container-type checks into verify_return_type helper
> ----------------------------------------------------------------------------
>
> Key: SPARK-56612
> URL: https://issues.apache.org/jira/browse/SPARK-56612
> Project: Spark
> Issue Type: Sub-task
> Components: PySpark
> Affects Versions: 4.2.0
> Reporter: Yicong Huang
> Assignee: Yicong Huang
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.3.0, 5.0.0
>
>
> Combine `verify_result` (iterator factory in
> `python/pyspark/sql/pandas/serializers.py`) and scattered container-type
> `isinstance` checks into a unified helper:
> {code:python}
> verify_return_type(result, expected_type, *, iterator=False)
> {code}
> Replace existing `verify_result` callers (SQL_SCALAR_ARROW_UDF and
> SQL_SCALAR_ARROW_ITER_UDF) with the unified form. This enables downstream
> refactors to replace inline `isinstance` checks with a single well-named
> helper across all eval types.
> Part of SPARK-55388.
