I routinely get this exception from cqlsh on one of my clusters: cql.cassandra.ttypes.AuthenticationException: AuthenticationException(why='org.apache.cassandra.exceptions.ReadTimeoutException: Operation timed out - received only 2 responses.')
The system_auth keyspace is set to replicate X times given X nodes in each datacenter, and at the time of the exception all nodes are reporting as online and healthy. After a short period (i.e. 30 minutes), it will let me in again. What could be the cause of this?
