Hi devs and users, This topic was originally discussed and reached a consensus in [1]. Because the change touches the pluggable shuffle interface, though not annotated as public currently, some users may be using it already. To avoid bring compatibility issues to customized shuffle plugins already implemented. I am writing a FLIP [2] which contains only the minimal changes and involving the user mailing list. If there is no objections, I will start a voting soon.
