我已经下载了 cassandra 的 DataStax 构建（dsc...-bin.tar.gz）并正确解压缩到 Solaris Server 机器上。根据http://wiki.apache.org/cassandra/GettingStarted/编辑配置目录后，我第一次尝试使用 ~/cassandra/bin 中的“./cassandra -f”启动 cassandra，但遇到异常导致堆栈跟踪的启动。

日志文件如下。

我在 Windows 机器上安装了相同版本的 cassandra（用于测试），但从未遇到过此类错误。如果 Cassandra 兽医可以帮助我，我将不胜感激。

问题出在 cassandra 依赖库中。显然，Cassandra 1.1.2（我正在使用）依赖于 Snappy Compression 的本机方法。Cassandra 1.1.0 不依赖本机方法，因此可以毫无问题地工作！
