Apache Spark reassigned SPARK-28356:
------------------------------------
Assignee: (was: Apache Spark)
> Do not reduce the number of partitions for repartition in adaptive execution
> ----------------------------------------------------------------------------
>
> Key: SPARK-28356
> URL: https://issues.apache.org/jira/browse/SPARK-28356
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Carson Wang
> Priority: Minor
>
> Adaptive execution reduces the number of post-shuffle partitions at runtime,
> even for shuffles caused by repartition. However, the user likely wants to
> get the desired number of partition when he calls repartition even in
> adaptive execution. It will be good to support not changing the number of
> post-shuffle partition for repartition in adaptive execution.
