Astyanax-尝试连接到cassandra时出现TokenRangeOfflineException

这就是我如何连接Cassandra，作者Astyanax：

Builder builder = new AstyanaxContext.Builder()
        .forCluster(clusterName)
        .forKeyspace(keyspace2)
        .withAstyanaxConfiguration(new AstyanaxConfigurationImpl()      
            .setDiscoveryType(NodeDiscoveryType.RING_DESCRIBE)
        )
        .withConnectionPoolConfiguration(new ConnectionPoolConfigurationImpl("MyConnectionPool")
            .setMaxConnsPerHost(2)
            .setInitConnsPerHost(2)
            .setSeeds("localhost,localhost")
        )
        .withConnectionPoolMonitor(new CountingConnectionPoolMonitor());
            AstyanaxConfigurationImpl config = new AstyanaxConfigurationImpl();
        config.setDefaultWriteConsistencyLevel(ConsistencyLevel.CL_QUORUM);
        config.setDefaultReadConsistencyLevel(ConsistencyLevel.CL_QUORUM);
        builder = builder.withAstyanaxConfiguration(config);

如果在种子中我只放了“localhost”，那么效果很好。 如果我放上“localhost，localhost”或“localhost”，它会给出下面的异常。 我会错过什么？问题不在于主机，地址是正确的。。。如果我使用CL_Quorum，是否有任何配置需要注意

我认为这与另一个问题有关。您只想使用localhost或种子列表。我们基本上会进行一些检测，如果您只使用一个节点，那么在使用localhost或写入和读取失败时，我们会使用clu one来保持一致性。我们为2个或更多的种子做CL_QUOROM。您是否需要我们对此进行修改以支持单个远程节点

谢谢， 院长
