> Key: SPARK-30074
> URL: https://issues.apache.org/jira/browse/SPARK-30074
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Yuanjian Li
> Assignee: Yuanjian Li
> Priority: Major
>
> The config "spark.sql.adaptive.shuffle.maxNumPostShufflePartitions" should be controlled by not only "spark.sql.adaptive.enabled", but also "spark.sql.adaptive.shuffle.reducePostShufflePartitions.enabled", that keeps the same behavior of minNumPostShufflePartitions and targetPostShuffleInputSize.
