In the internal version of the fix, we receive any event that implements rewatch. The following log shows that it received `Watcher.Event.EventType#None`. ``` 24/06/17 07:33:14,909 [main-EventThread] WARN ZookeeperDiscoveryClient: This Kyuubi instance xxx (znode null) receives None 24/06/17 07:33:17,201 [main-EventThread] INFO ConnectionStateManager: State change: SUSPENDED 24/06/17 07:33:17,202 [main-EventThread] WARN ZookeeperDiscoveryClient: This Kyuubi instance xxx:xx (znode null) receives None ``` ### Implementation steps DeRegisterWatcher should re-watch when any event is received ### Additional context Introduction of [2024H1 Kyuubi Code Contribution Program](https://github.com/apache/kyuubi/issues/6232) -- This is an automated message from the Apache Git Service.
