Estou correndo para esse erro em um nó do OpsCenter com o DSE Cassandra instalado localmente. Ele está em seu próprio DC e faz parte de um cluster com três outros nós em outro DC.
A autenticação é ativada no cluster com org.apache.cassandra.auth.PasswordAuthenticator e org.apache.cassandra.auth.CassandraAuthorizer. A tabela system_auth é replicada em todos os nós no cluster com estratégia de replicação simples e fator de replicação de 4.
[cqlsh 5.0.1 | Cassandra 2.1.5.469 | DSE 4.7.0 | Especificação CQL 3.2.0 | Protocolo nativo v3]
Do Cassandra system.log no nó do OpsCenter:
