> Project: Spark
> Issue Type: Sub-task

> Affects Versions: 3.3.0
> Reporter: jiaan.geng
> Assignee: Apache Spark
> Priority: Major

> Currently, Spark provides UnevaluableAggregate to replace function with another function which must be exists in build-in functions, so UnevaluableAggregate make Spark could reuse the implement of build-in function.
> However, the sub classes of UnevaluableAggregate looks cumbersome.
