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 混合 n=2000000 -pop seq=1..2000000 -rate thread=2000 -node 10.10.0.1

它开始根据命令执行，但有时它开始给出如下错误

com.datastax.drivers.core.exceptions.NoHostAvailableExcception：所有主机查询失败（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

您需要在读取数据之前写入数据。

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
