fcb-xiaobo opened a new issue, #8871: URL: https://github.com/apache/seatunnel/issues/8871
### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened During the testing process, I found an exception in the jedissWrapper. select (dbNum) method. I checked the official website and found that redisCluster does not support selecting db. If the select method is used, an error will be reported. Therefore, I will briefly raise an issue and try to fix it   https://redis.io/docs/latest/operate/oss_and_stack/reference/cluster-spec/  ### SeaTunnel Version 2.3.9 ### SeaTunnel Config ```conf # # Licensed to the Apache Software Foundation (ASF) under one or more # contributor license agreements.
