使用Cassandra Java驱动程序播放2.x - 错误com.datastax.driver.core.Session - 创建池到xxx.xx时出错，但返回响应

Set up

• Cassandra Java驱动程序：2.1.3,2.1.4,2.0.0（全部试用）

• Cassandra集群：[cqlsh 5.0.1 | Cassandra 2.1.0 | CQL规范3.2.0 |原生协议v3]

• 播放2.2.3

我在访问简单表时遇到上述设置问题 . 但我也得到了日志中的回复 . 我在EC2,2节点单数据中心上运行服务器 . 也尝试使用EC2 AMI但结果相同 . 此外，这是一个非常新鲜的设置，并且还没有加载服务器 .

Cassandra Configs

rpc_address : 0.0.0.0
listen_address : internal_ip
broadcast_address: public_ip
start_native_transport: true
native_transport_port: 9042

Code snippet

SocketOptions options = new SocketOptions();
        options.setConnectTimeoutMillis(10000);
        options.setReadTimeoutMillis(10000);

        cluster = Cluster.builder().addContactPoints("public_ip1","public_ip2").withPort(9042).withSocketOptions(options).withRetryPolicy(DowngradingConsistencyRetryPolicy.INSTANCE)
                .withReconnectionPolicy(new ConstantReconnectionPolicy(1000L)).build();

         Metadata metadata = cluster.getMetadata();
         System.out.printf("Connected to cluster: %s\n", 
                metadata.getClusterName());

        session = cluster.connect();

        // Use select to get the user we just entered
        ResultSet results = session.execute("SELECT * FROM redmart.user_pick_rate");
        for (Row row : results) {
            System.out.println( "user_id : " + row.getInt("user_id") + " pick_rate : " + row.getDouble("pick_rate"));
        }

根据以下异常，它总是向Java客户端中的一个节点抱怨“将池创建到/ internal_ip：9042” . 例如，如果我有node1，node2 . 在javaclient中如果我只用node1创建一个集群，它抱怨无法创建池（node2的内部ip），如果我使用节点2来创建集群，它就会抱怨无法创建池到（node1的内部ip） . 如果我指定它们总是说错误创建池到其中一个节点 . 我尝试过不同的netty版本 .

我在here中看到了类似的未解决的问题，但在我的情况下，我也得到了回复 .

任何见解都表示赞赏 .
