> There are two paths for Spark set reducer parallelism, depending on the config {{hive.spark.use.op.stats}}. We currently handle all the logic in {{SetSparkReducerParallelism}}, and the logic is a bit complicated. Ideally we should refactor this to make it clearer, perhaps with separate rules for the paths.
