### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [X] I have searched in the [issues](https://github.com/apache/incubator-uniffle/issues?q=is%3Aissue) and found no similar issues. ### Describe the bug The hadoop filesystem instance will be created too many time in cache, which will cause the shuffle server memory leak. As we know, the filesystem cache's key is based on the schemećauthority and ugi. The scheme and authority are not changed everytime. But for ugi, if we invoke the createProxyUser, it will always create a new one, that means the every invoking `Filesystem.get()` , it will be cached due to different key. We should cache the proxy user ugi to avoid caching every time. ### Affects Version(s) master ### Uniffle Server Log Output _No response_ ### Uniffle Engine Log Output _No response_ ### Uniffle Server Configurations _No response_ ### Uniffle Engine Configurations _No response_ ### Additional context _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
