Anthony Cozzie updated CASSANDRA-8640:
--------------------------------------
Description:
{code}
int requiredParticipants = participants + 1 / 2; // See CASSANDRA-833
{code}
Will always return participants because of operator precedence. 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}
was:
{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}
