Hello
Recently, I encountered the following two issues in using Kylin 4.0.3, which are difficult to solve and require your Q&A: 1. A test topic test0718 was created in Kylin, and data was constructed on this topic and queried. A log of - [QUERY] - will be printed every second in Kylin.log, with SQL in query being select 1; Execute once per second; 2. After deleting the test topic test0718 in kylin, an error is reported every ten minutes in kylin.log. The error is: controller. BasicController: 98: Org. apache. kylin. test. exception. BadRequestException: Cannot find project 'test0718'; May I ask how the above two situations were triggered? Thank you~
