Aleksey Yeschenko commented on CASSANDRA-9467: ---------------------------------------------- It behaved like that a long long time ago. While it would be nice to bring back that behaviour - it's convenient, during a live upgrade, to not have both versions present - it's not currently a high priority issue for us. > cqlsh does not connect to older protocol versions > ------------------------------------------------- > > Key: CASSANDRA-9467 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9467 > Project: Cassandra > Issue Type: Bug > Environment: 2.2rc1 against 2.1 / 2.0 > Reporter: Robert Stupp > Assignee: Stefania > Labels: cqlsh > Fix For: 2.2.0 rc1 > > > {{cqlsh}} (from curent 2.2 branch) does no longer work against C* 2.1 and 2.0. > {code} > bin/cqlsh > Connection error: ('Unable to connect to any servers', {'127.0.0.1': > ConnectionException('Did not get expected SupportedMessage response; instead, > got: Server protocol version (3) does not match the specified driver protocol > version (4).
