Cassandra的文件结构以及如何在Cassandra Cluster Manager(CCM)中指定其目录？

我已经按照Ubuntu 14.04 LTS上的DATASTAX文档成功安装了Cassandra-2.0.9 .为了快速测试本地计算机上的集群,我安装了Cassandra Cluster Manager(CCM)工具.

要创建集群,请ccm create --cassandra-dir *** --nodes 3 --start test发出类似命令,该命令应设置并启动名为"test"的3节点集群.但是,我不确定cassandra目录在我当前的安装下是什么.

我的问题:

什么cassandra-dir应该被指定？

Cassandra文件是如何组织的？作为Ubuntu的新手,我对分散在不同目录中的文件感到很困惑.

PS:该命令dpkg -L cassandra提供以下Cassandra相关文件列表.如果您需要更多信息,请随意询问.谢谢.

CCM不使用二进制Cassandra安装,它总是从源代码构建(它最初是一个开发工具).

--cassandra-dir 是什么时候你想把它指向一个现有的源目录(通常,当你攻击Cassandra并想要尝试修改后的版本时).

否则,您只需给它一个Cassandra版本,它将为您下载并编译源代码:

ccm create my_cluster_name -v 2.0.9

我不知道你是否已经看过它,但GitHub上的README包含有用的信息.
