### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version Version : doris-2.1.5-rc02 BuildInfo : iZ2ze9pz2eap5besutxc7oZ BuildTime : Sat, 20 Jul 2024 22:29:36 CST ### What's Wrong? When adding the FE, I used a lowercase hostname (e.g., server02:9010), but the actual hostname is uppercase Server02. This caused the main FE to report the following error: WARN (qtp1694355353-190|190) [MetaService.isFromValidFe():71] request is not from valid FE. client: Server02, 9010. However, the same setup in the BE does not result in an error. Additionally, when attempting to drop an already added node, the BE can drop the corresponding node regardless of the case, while the FE reports that it cannot find the node. (I know the best way to avoid this is using ip address instead.) ### What You Expected? Fix it. ### How to Reproduce? If you are running a host with hostname in lower case, try to `ALTER SYSTEM ADD FRONTEND "Uppercase:port"`, vice versa. You can try the same procedure in adding BE nodes to reproduce this situation. ### Anything Else? _No response_ ### 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.
