Stefania commented on CASSANDRA-12150:
--------------------------------------
Thanks for the review. Committed to trunk as
74647a8cc5b18b86ee5cfdb071a8644630a1e7f3 with the following in NEWS.txt:
{code}
- cqlsh can now connect to older Cassandra versions by downgrading the native
protocol version. Please note that this is currently not part of our release
testing and, as a consequence, it is not guaranteed to work in all cases.
See CASSANDRA-12150 for more details.
{code}
We can consider adding a warning later on if, as you said, it causes frequent
problems.
> cqlsh does not automatically downgrade CQL version

> Key: CASSANDRA-12150

> Project: Cassandra
> Issue Type: Improvement

>
> 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?
