Stefania commented on CASSANDRA-12150:
--------------------------------------
We should probably mention somewhere that, even though cqlsh now connects to
older server versions, there may be problems and it may not work in all cases
since we currently do not test cqlsh against older server versions,
[~iamaleksey] are we OK with this?
> cqlsh does not automatically downgrade CQL version

> Key: CASSANDRA-12150
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12150
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL
> Reporter: Yusuke Takata
> Priority: Minor
> Labels: cqlsh
> Attachments: patch.txt
>
>
> Cassandra drivers such as the Python driver can automatically connect a
> supported version,
> but I found that cqlsh does not automatically downgrade CQL version as the
> following.
> {code}
> $ cqlsh
> Connection error: ('Unable to connect to any servers', {'127.0.0.1':
> ProtocolError("cql_version '3.4.2' is not supported by remote (w/ native
> protocol). Supported versions: [u'3.4.0']",)})
> {code}
> I think that the function is useful for cqlsh too.
> Could someone review the attached patch?
