### What would you like to be improved?

Currently, we don't know which shuffle server the client is committing to.
```

```
We can add the shuffle server's IP and port into the log.

### How should we improve?

_No response_

### Are you willing to submit PR?

- [X] Yes I am willing to submit a PR!

Start at RssShuffleWriter.sendCommit, where the existing wait-commit log is emitted. Trace the shuffle server target available at that point and include its IP and port in the message; the work is done when the commit log identifies the server. No test file is named in the issue, so inspect the existing tests around this entry point.
