>
> Function CheckCompleteReplace in replace rebalance will try to make the
> leader step down if the replica, which should be removed, is leader, but this
> may stuck for a while if the replication factor of the table is 1, since
> there is no voter to transfer leadership.
> So it will be ok if we make sure voter num of the tablet is greater than 1
> before sending the LeaderStepDown request.
