Song Jiacheng updated KUDU-3487:
--------------------------------
Description:
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.
So it will be ok if we make sure voter num of the tablet is greater than 1
before sending the LeaderStepDown request.
