Summary: Incorrect connected node metric when session is closed and reinitted in same JVM Key: CASSANDRA-19388 URL: https://issues.apache.org/jira/browse/CASSANDRA-19388 Project: Cassandra Issue Type: Bug Components: Client/java-driver Reporter: Nitin Chhabra Assignee: Henry Hughes We observed incorrect connected nodes metric reported when session is closed and re-initted. *Setup* Java 8 Java Driver Version: 4.15.0 Cassandra Server: 4.X 3 nodes in Azure West *Steps to reproduce the issue* # Init the CQLSession successfully. # Observe the connected nodes metric is 3. # Stop the session gracefully by calling: session.closeAsync() and wait for few seconds for close. # _Reinit the CQLSession and monitor the connected nodes metric. It goes down to 1._ *Triage/Troubleshooting* On Cassandra Server side, we can observe connections made to all 3 nodes. Upon further debugging by putting some log statements and modifying the driver, it appears the NodeStateManager updates its open connection count to 3, however MetaDataManager does not show all 3 nodes have active connections. Please let me know if more info is needed.
