There was a problem hiding this comment.
These three test cases are moved to SparkSqlParserSuite.scala

…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 <gatorsmile@gmail.com> Closesapache#16988 from gatorsmile/resolveRepartition.
