Stefania commented on CASSANDRA-12150:
--------------------------------------
+1, I've also removed {{DEFAULT_CQL_VERSION}}.
I'm not sure we need {{--cqlversion}} at all, given that a server will not
accept an older version, but I've left it for backward compatibility.
Test results are still pending:

> cqlsh does not automatically downgrade CQL version

>
> 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?
