      Description

      For fixing the correctness bug of SPARK-28699, we disable radix sortĀ for the scenario of repartition in Spark SQL. This will cause a performance regression.

      So for limiting the performance overhead, we'll do the optimizing work by only enable sort before repartition config for the retried stage. This work depends on SPARK-25341.
