                 Key: ZOOKEEPER-1343
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1343
             Project: ZooKeeper
          Issue Type: Bug
            Reporter: Flavio Junqueira
            Assignee: Flavio Junqueira


The following block in Leader.getEpochToPropose:

{noformat}
if (lastAcceptedEpoch > epoch) {
        epoch = lastAcceptedEpoch+1;
}
{noformat}

needs to be fixed, since it doesn't increment the epoch variable in the case 
epoch != -1 (initial value) and lastAcceptedEpoch is equal. The fix trivial and 
corresponds to changing > with >=.
