> Refactor common partitioning/distribution logic to BaseAggregateExec
> --------------------------------------------------------------------
>
> Key: SPARK-32740
> URL: https://issues.apache.org/jira/browse/SPARK-32740
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Cheng Su
> Priority: Trivial
>
> For all three different aggregate physical operator: `HashAggregateExec`,
> `ObjectHashAggregateExec` and `SortAggregateExec`, they have same
> `outputPartitioning` and `requiredChildDistribution` logic. Refactor these
> same logic into their super class `BaseAggregateExec` to avoid code
> duplication and future bugs (similar to `HashJoin` and `ShuffledJoin`).
