But we provide the method of `createShuffleIOOwnerMetricGroup` in factory, and it is only used for adding group simple. So it might bring confused that which `addGroup` should be done inside factory and which should be done outside. The scope/rule seems not clear. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
