> Key: SPARK-39915

> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Shixiong Zhu
> Priority: Major
>
> Looks like there is a behavior change in Dataset.repartition in 3.3.0. For example, `spark.range(10, 0).repartition(5).rdd.getNumPartitions` returns 5 in Spark 3.2.0, but 0 in Spark 3.3.0.
