cassandra之DataStax Java 驱动程序 2.0.0-beta2 与 Cassandra 1.2.1 : unsupported protocol version

我想知道 com.datastax.cassandra:cassandra-driver-core:2.0.0-beta2 是否可以与 org.apache.cassandra:cassandra-all:1.2.1 一起使用。我正在使用 cassandra-maven-plugin:1.2.1-1(它使用 org.apache.cassandra:cassandra-all:1.2.1)，添加

start_native_transport: true 
native_transport_port: ${cassandra.nativePort} 

到 yaml插件属性。我可以成功 telnet 到该端口。

但是，当我尝试通过以下代码进行连接时，

// Ports.NATIVE has the same value as "${cassandra.nativePort}" above 
Cluster cluster = Cluster.builder().addContactPoint("127.0.0.1") 
    .withPort(Ports.NATIVE).build(); 
Session session = cluster.connect(); 

我收到以下异常:

com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /127.0.0.1 (com.datastax.driver.core.ConnectionException: [/127.0.0.1] Unexpected error during transport initialization (com.datastax.driver.core.TransportException: [/127.0.0.1] Unexpected exception triggered (com.datastax.driver.core.exceptions.DriverInternalError: Server response from unsupported protocol version: 1)))) 
    at com.datastax.driver.core.ControlConnection.reconnectInternal(ControlConnection.java:179) 
    at com.datastax.driver.core.ControlConnection.connect(ControlConnection.java:77) 
    at com.datastax.driver.core.Cluster$Manager.init(Cluster.java:868) 
    at com.datastax.driver.core.Cluster$Manager.newSession(Cluster.java:888) 
    at com.datastax.driver.core.Cluster$Manager.access$200(Cluster.java:792) 
    at com.datastax.driver.core.Cluster.connect(Cluster.java:155) 

我认为它的关键是 Server response from unsupported protocol version: 1 .

这是否意味着 2.0.0-beta2 驱动程序不能与 Cassandra 1.2.1 一起使用？驱动程序/服务器兼容性矩阵在哪里？

我已经为此烧了将近一天。

谢谢，

请您参考如下方法:

是的，不兼容。 From the java-driver 2.0 requirements :

The driver uses Casandra's native protocol, and this version 2.0 uses the second version of that protocol. As such, this version of the driver requires a version of Cassandra greater than or equal to 2.0 (for Cassandra 1.2 please use the version 1.0 of the driver).

尝试降级到 1.0，最新版本是 1.0.4:

<dependency> 
  <groupId>com.datastax.cassandra</groupId> 
  <artifactId>cassandra-driver-parent</artifactId> 
  <version>1.0.4</version> 
</dependency>
