Hello everyone! I am seeing recent behavior of apps being not able to communicate to the Cassandra cluster with the following errors:
All host(s) tried for query failed (tried: cassandra2-test:9042 (com.datastax.driver.core.exceptions.DriverException: Timeout while trying to acquire available connection (you may want to increase the driver number of per-host connections)), cassandra3-test:9042 (com.datastax.driver.core.exceptions.TransportException: [cassandra3-test/] Connection has been closed), cassandra1-test:9042 (com.datastax.driver.core.exceptions.TransportException: [cassandra1-test/] Connection has been closed)) I have enabled start_native_transport already but this does not fix the problem. I would appreciate any feedback on the problem. Thanks, Ivan
