> BatchScanExec equals/hashCode contract violations
> -------------------------------------------------
>
> Key: SPARK-56444
> URL: https://issues.apache.org/jira/browse/SPARK-56444
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.0.0
> Reporter: Anton Lykov
> Priority: Major
> Labels: pull-request-available
>
> BatchScanExec.equals() violates reflexivity when batch is null (which happens
> after serialization round-trip since scan is @transient) — x.equals(x)
> returns false. Additionally, hashCode() does not include
> keyGroupedPartitioning despite equals() comparing it, violating the
> equals/hashCode contract.
