需要一些有关 cassandra 压力测试的帮助。我已经从 datastax 网站安装了 cassandra-stress 2.1 工具。我想以 10:1 的比例并使用 15 个线程进行读+写压力测试。我不知何故无法让它工作。我能够成功地分别进行读写测试。

我正在使用的命令： ./cassandra-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 -节点 192.168.5.10

即使我将端口指定为 9160，但它使用的是本机 9042 端口。

我收到以下错误：

    ERROR 18:03:07 Error creating pool to /192.168.5.11:9042

您需要转义 shell元字符（在这种情况下是括号和尖括号）。尝试这个：

./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
