> Non-deterministic hashCode() calculations for ArrayBasedMapData on equal
> objects
> --------------------------------------------------------------------------------
>
> Key: SPARK-40315
> URL: https://issues.apache.org/jira/browse/SPARK-40315
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.2.2
> Reporter: Carmen Kwan
> Priority: Major
>
> There is no explicit `hashCode()` function override for the
> `ArrayBasedMapData` LogicalPlan. As a result, the `hashCode()` computed for
> `ArrayBasedMapData` can be different for two equal objects (objects with
> equal keys and values).
> This error is non-deterministic and hard to reproduce, as we don't control
> the default `hashCode()` function.
> We should override the `hashCode` function so that it works exactly as we
> expect. We should also have an explicit `equals()` function for consistency
> with how `Literals` check for equality of `ArrayBasedMapData`.
