cassandra - 连接到两个节点集群时出现 astyanax TokenRangeOfflineException

Question

我编写了一些相当简单的代码来试验 astyanax。当与本地主机上的单节点 Cassandra 数据库通信时，它工作正常，但是当我将相同的架构写入两节点集群(绝对可以从我的主机访问)时，我得到一个 TokenRangeOfflineException 。 p>

我错过了什么？

AstyanaxContext.Builder builder = new AstyanaxContext.Builder()
            .forKeyspace("myKeyspace")
            .withAstyanaxConfiguration(new AstyanaxConfigurationImpl()
                    .setDiscoveryType(NodeDiscoveryType.NONE)
            )
            .withConnectionPoolConfiguration(new ConnectionPoolConfigurationImpl("MyConnectionPool")
                    .setPort(9160)
                    .setMaxConnsPerHost(5)
                    .setSeeds("host1.domain.com,host2.domain.com")
            )
            .withConnectionPoolMonitor(new CountingConnectionPoolMonitor());

产生此错误:

尝试使用NodeDiscoveryType.RING_DESCRIBE
