### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened After successfully creating a hive data source from the ds page, execute the command in hive to delete the db corresponding to the ds. After about 20 minutes, the apiserver starts to report the error that the connection to the db is not possible, and it keeps reporting errors, resulting in hive connection number is filled. This data source has not been used anywhere in ds since the page was created. ### What you expected to happen Only when using it report the error that the connection cannot be made ### How to reproduce 1. Create a hive data source on the page, select a database that exists in hive, such as testdb, and add it successfully 2. Beeline logs in to hive where the db created in step 1 is located, and executes the name drop database testdb; 3. Observe the apiserver. log, and find that after about 20 minutes (or directly go to the page to edit the data source created in step 1, click Test Connection), an error that this database does not exist starts to report, and it keeps looping, which eventually leads to too many hive connections. ### Anything else _No response_ ### Version 2.0.5 ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
