-----------------------------------
Labels: pull-request-available (was: )
> Fix GROUP BY MapType feature
> ----------------------------
>
> Key: SPARK-48619
> URL: https://issues.apache.org/jira/browse/SPARK-48619
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.4.3
> Reporter: Stevo Mitric
> Priority: Major
> Labels: pull-request-available
>
> There are issues in the current implementation, which causes broken plans to
> be produced:
> * The InsertMapSortInGroupingExpressions transformation only replaces the
> grouping expressions with mapsort, not the aggregate expressions. This causes
> broken plans like select c from t group by mapsort(c), where c now becomes a
> non-aggregating expression.
> * Parent operators referencing the transformed columns are not updated,
> which means that we know have broken references.
