             Summary: Paxos requires all nodes for CAS
                 Key: CASSANDRA-8640
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8640
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Anthony Cozzie
            Assignee: Sylvain Lebresne


{code}
int requiredParticipants = participants + 1  / 2; // See CASSANDRA-833
{code}

Fails owing to the order of operations.  I am not sure just adding parentheses will fix the problem, though, as the original code differentiated between pending and natural endpoints.

{code}
 int requiredParticipants = pendingEndpoints.size() + 1 + naturalEndpoints.size() / 2; // See CASSANDRA-833
{code}
