Question

我已经在具有centos 7的服务器上安装了cassandra 3.0.9，同时尝试使用以下命令执行cassandra-stress

cassandra-stress mixed n = 2000000 -pop seq = 1..2000000 -rate thread = 2000 -node 10.10.0.1

它根据命令开始执行但有时它开始给出如下所示的错误

com.datastax.drivers.core.exceptions.NoHostAvailableExcception：查询失败的所有主机（已尝试：10.10.0.1/10.10.0.1:9042(com.datastax.driver.core.exceptions.TransportException：[10.10] .0.1 / 10.10.0.1]连接已关闭））

有时会出现如下错误

Answer 1

您需要在阅读之前编写数据。

首先执行： cassandra-stress write n=2000000 -pop seq=1..2000000 -rate threads=2000 -node 10.10.0.1

然后你可以执行：cassandra-stress mixed n=2000000 -pop seq=1..2000000 -rate threads=2000 -node 10.10.0.1

Cassandra-Stress因错误而停止
