Or steps for how to connect Net beans & Cassandra.

推荐答案

默认情况下，Cassandra默认不进行身份验证和授权.

By default, Cassandra defaults to no authentication and no authorization.

在您的Cassandra安装中，打开conf文件夹中的cassandra.yaml并设置:

In your Cassandra installation, open cassandra.yaml in conf folder and set:

authenticator: PasswordAuthenticator
authorizer: CassandraAuthorizer

重新启动Cassandra服务器. (nodetool stopdaemon可用于停止)

Restart your Cassandra server. ( nodetool stopdaemon can be used to stop)

之后，您应该可以使用以下用户名登录:用户名:cassandra和密码:cassandra

After that you should be able to login with: Username: cassandra and Password: cassandra
