### Are you willing to submit PR?

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

Start by locating the existing RPCs that expose the uniffleShuffleId and the Write Stage retry path in the Java codebase. Confirm how the new RPC should return the ID and which relevant retry code should be removed; the work is done when both behaviors are implemented consistently.
