jiajunwang commented on issue #660: Controller leader switch may trigger some additional (unexpected) rebalance in the WAGED rebalancer URL: https://github.com/apache/helix/issues/660#issuecomment-575539052 I tried some options. The step one mentioned before is doable. But step two is concerning because of one case. If a new instance joining the cluster at the moment of a leadership switch, we might end up assign nothing to it since the baseline will only assign newly added resources. So before we confirm if there is any real problem, let's just keep the original design that the leadership switch will cause the rebalancer to re-evaluate all partitions assignment.
