Description

With 1.2.2, I am using the new authentication backend PasswordAuthenticator with the authorizer CassandraAuthorizer

In case of network outage, we are no more able to connect to Cassandra.

Here is the error message we get when I want to connect through cqlsh:
Traceback (most recent call last):
