### 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 I use docker to deploy master, I have 2 master. when I restart them by ansible: 1. master1 stop，remove zk node: `nodes/master/master1` 2. master1 start, remove zk node：`nodes/dead-servers/master1` 3. master2 watch master1 down, add zk node：`nodes/dead-servers/master1` 4. master1 watch add zk node：`nodes/dead-servers/master1`，master1 kill itself. stop quartz will auto close jdbc connection , and every zk watch event will throw `com.alibaba.druid.pool.DataSourceClosedException: dataSource already` so if you have multi master , and quickly restart one if them , the master just can not restart succesfully. ### What you expected to happen anytime restart the master ,it can just restart success ### How to reproduce when watch master down, should check the master is not exist in `nodes/master/master1` and then add it to `nodes/dead-servers/master1` ### Anything else _No response_ ### Version 1.3.6 ### Are you willing to submit PR? - [ ] 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.
