Dongjoon Hyun reopened SPARK-53074:
-----------------------------------
> Avoid partially clustered distribution when key-grouped partitioning used to
> satisfy non-JOIN required distribution
> -------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-53074
> URL: https://issues.apache.org/jira/browse/SPARK-53074
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.3.0, 3.4.0, 3.5.0, 4.1.0, 4.0.0
> Reporter: Chirag Singh
> Assignee: Chirag Singh
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.1.0, 4.0.1
>
>
> Currently, SPJ logic can apply partial clustering (when enabling) to either
> side of an inner JOIN as long as the nodes between the scan and JOIN preserve
> partitioning. This doesn't work if one of these nodes is using the scan's
> key-grouped partitioning to satisfy its required distribution (for example, a
> grouping agg or window function).
