Am trying to connect from Datastax java driver to cassandra secure cluster with kerberos enabled.

Sample connection code:

    cluster = Cluster.builder().addContactPoint(node).withCredentials("username","password").build();
    Metadata metadata = cluster.getMetadata();
    System.out.printf("Connected to cluster: %s\n",
            metadata.getClusterName());
    for (Host host : metadata.getAllHosts()) {
        System.out.printf("Datatacenter: %s; Host: %s; Rack: %s\n",
                host.getDatacenter(), host.getAddress(), host.getRack());

    }
    session = cluster.connect();

Am getting the below error:

Exception in thread "main" com.datastax.driver.core.exceptions.AuthenticationException: Authentication error on host /x.x.x.x: java.lang.RuntimeException: javax.security.auth.login.LoginException: Unable to obtain password from user

在您的代码示例中，您使用用户名/密码凭据进行身份验证，这不适用于 Kerberos。这篇博文包含有关在安全 DSE 集群中使用 java 驱动程序的详细信息：http ://www.datastax.com/dev/blog/accessing-secure-dse-clusters-with-cql-native-protocol
