在cassandra 2.1包安装中使用cassandra-stress时出现连接被拒绝错误

Question

我正在尝试使用cassandra stress工具在一个3节点集群上填充一些数据。我试着多次运行casssandra的压力，但我得到了错误。有人能告诉我哪里出了问题吗？

enter code here`Exception in thread "main" java.lang.RuntimeException:     org.apache.thrift.transport.TTransportException: java.net.ConnectException: Connection refused

原因: org.apache.thrift.transport.TTransportException:在org.apache.thrift.transport.TFramedTransport.open(TFramedTransport.java:81)在org.apache.cassandra.thrift.TFramedTransportFactory.openTransport(TFramedTransportFactory.java:41)在org.apache.cassandra.stress.settings.StressSettings.getRawThriftClient(StressSettings.java:124)的org.apache.thrift.transport.TFramedTransport.open(TFramedTransport.java:81)连接被拒绝... 6更多

我也面临着同样的问题。为了解决这个问题，我又添加了一个参数"-node“

因此，我的cassandra-stress命令如下所示：

cassandra-stress write n=50000 -rate threads=40 -node d0.cass.org

其中，d0.cass.org是群集中某个节点的主机名。
