混合载荷卡桑德拉应力测试

Question

需要一些关于cassandra压力测试的帮助。我已经从datastax网站安装了cassandra压力2.1工具。我想以10:1的比例使用15个线程进行读写压力测试。不知何故，我无法让它工作。我能够成功地分别进行读写测试。

我正在使用的命令：./cassandra-压力混合比率（write=1， read=10）n=10000 cl=ONE-端口节俭=9160-架构keyspace="Keyspace1"-模式节俭智能速率线程

尽管我将端口指定为9160，但它使用的是本机9042端口。

我得到以下错误:

您需要转义壳元字符（在本例中为旁白和尖括号）。试试这个：

./cassandra-stress mixed ratio\(write=1,read=10\) n=10000 cl=ONE -port thrift=9160 -schema keyspace="Keyspace1" -mode thrift smart -rate threads\>=15 threads\<=15 -node 192.168.5.10
