Stefania commented on CASSANDRA-11950:
--------------------------------------
I've modified the test code to avoid the {{UnknownColumnFamilyException}}
warnings in the logs, by leveraging
{{session.cluster.control_connection.wait_for_schema_agreement}}, changes are
[here|https://github.com/stef1927/cassandra-dtest/commits/11950].
Before I create the pull request, I want to wait on another pull request I've
created for the driver
[here|https://github.com/datastax/python-driver/pull/615]: it seems there is a
problem in that replicas for which there is no connection are excluded, as well
as remote replicas unless we use a DC aware load balancing policy that contacts
remote hosts as well. I want to confirm we really need to change the load
balancing policy, or whether we can change the behavior in the driver, cc
