Question

我正在使用Cassandra 3.7。我正在使用AuthProvider进行身份验证。我尝试了两种方法：

AuthProvider authProvider = new PlainTextAuthProvider("abcd", "xyz");
Cluster cluster = Cluster.builder().addContactPoint(node).withAuthProvider(authProvider).build();
Session session = cluster.connect();

和

Cluster cluster = Cluster.builder().addContactPoint(node)..withCredentials("abcd", "xyz").build();
Session session = cluster.connect();

我收到以下错误：

Exception in thread "main" com.datastax.driver.core.exceptions.AuthenticationException: Authentication error on host /127.0.0.1:9042: Host /127.0.0.1:9042 requires authentication, but no authenticator found in Cluster configuration
    at com.datastax.driver.core.AuthProvider$1.newAuthenticator(AuthProvider.java:40)

导致错误的原因是什么？如何解决？

Answer 1

更改cassandra.yaml中的身份验证器和授权程序的值：

authenticator：PasswordAuthenticator

授权人：CassandraAuthorizer

如何使用Java身份验证连接到Cassandra集群？
