### 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. ### What would you like to be improved? If we use multiple replicas and the first shuffle server becomes unavailable, sending data will take a lot of time. Because the client will always send to the first shuffle server firstly. ### How should we improve? If sending data to shuffle server failed, put it to the end of the server list before sending data. ### 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.
