             Summary: Rebalancer: Balance for 1 replication factor tablet might 
stuck for leader step down too early
                 Key: KUDU-3487
                 URL: https://issues.apache.org/jira/browse/KUDU-3487
             Project: Kudu
          Issue Type: Bug
    Affects Versions: 1.14.0
            Reporter: Song Jiacheng
         Attachments: 
Fix_a_bug_that_replace_balance_for_1_replication_factor_tablet_might_stuck_for_leader_step.patch

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 send the LeaderStepDown request.
