### 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 从ds页面创建成功一个hive数据源后，到hive里面执行命令把这个ds对应的db删除，过了大概20分钟左右，apiserver就开始报连接不上db的错误，而且是一直报错，导致hive连接数被占满。从页面创建这个数据源以后，就没有在ds任何一个地方使用过这个数据源。 ### What you expected to happen 只有在使用的时候报 连接不上的错误 ### How to reproduce 1. 页面创建hive数据源，选择某一个hive存在的数据库 比如 testdb，添加成功 2. beeline 登录1步骤创建的db所在hive，并执行命名 drop database testdb; 3. 观察apiserver.日志，发现大约20分钟多后(或者直接去页面编辑1步骤创建的数据源，点击测试连接) 开始报此数据库不存在的错误，而且一直循环，最终导致hive连接数过大 ### 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.
