Tyler Hobbs commented on CASSANDRA-12150:
-----------------------------------------
bq. I would need a code review of this commit, Tyler Hobbs would you be able to
review it?
+1 on that commit.
bq. 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
Yes, I think we should at least put something in {{NEWS.txt}} for now. Perhaps
if this causes frequent problems, we can have cqlsh print a warning when the C*
version it connects to is different than the C* version it shipped with.

>
> 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?
