   @caffreyZ Actually, it is not a good practice to use hiveserver2 for scheduled hive tasks in production. Hiveserver2 is a better choice for ad-hoc query. For scheduling purpose, you may try hive CLI. You could do it with shell task if you are using an old version of DS. If you are planning to upgrade DS, there will be a new `Hive CLI` task in the future. see: https://github.com/apache/dolphinscheduler/pull/11651
