…rser ### What changes were proposed in this pull request? Currently, if `NumPartitions` is not set in RepartitionByExpression, we will set it using `spark.sql.shuffle.partitions` during Planner. However, this is not following the general resolution process. This PR is to set it in `Parser` and then `Optimizer` can use the value for plan optimization. ### How was this patch tested? Added a test case. Author: Xiao Li <[email protected]> Closes apache#16988 from gatorsmile/resolveRepartition.
