在Cassandra上使用cassandra应力时，拒绝连接拒绝错误2.1软件包安装 [英] Getting Connection refused error while using cassandra-stress on cassandra 2.1 Package installation

问题描述

我尝试使用cassandra应力工具在3节点群集上填充一些数据。我试图运行casssandra压力多次，但我有低于错误。有人可以告诉我什么是错的。

I am trying to populate some data using cassandra stress tool on a 3 node cluster. I tried to run the casssandra stress multiple times but I got below error. can someone suggest me what is wrong.

推荐答案

我也面临同样的问题。要解决它，我再加一个参数-node

I was also facing the same issue. To solve it, I added one more argument "-node "

所以我的cassandra压力命令变成如下：

So my cassandra-stress command became as follows:

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

其中d0.cass.org是集群中某个节点的主机名。

Where d0.cass.org is the hostname of one of the nodes in the cluster.
