I've created a new PR and will move to review after CI tests complete. > Topology events are not sent to clients if the nodes use the same network > interface > ----------------------------------------------------------------------------------- > > Key: CASSANDRA-15677 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15677 > Project: Cassandra > Issue Type: Bug > Components: Messaging/Client > Reporter: Alan Boudreault > Assignee: Bryn Cooke > Priority: Normal > Labels: pull-request-available > Fix For: 4.0-rc > > Time Spent: 1h > Remaining Estimate: 0h > > *This bug only happens when the cassandra nodes are configured to use a > single network interface (ip) but different ports.
