使用 Cassandra 配置的 Spark

Question

在 cassandra 上运行 spark 得到 TTransportException。谁能告诉我，我必须进行任何配置才能通过 spark 访问 cassandra db 吗？
我将以下变量设置为 .bashrc & conf/spark-env.sh 文件：

export SCALA_HOME=/opt/scala-2.10.3

Answer 1

看看这个库 http://tuplejump.github.io/calliope/ 用于 spark cassandra 集成。DataStax 还发布了一个 Spark 驱动程序，可以在这里找到 https://github.com/datastax/spark-cassandra-connector

Answer 2

我已经成功尝试了这个blog 指令。

测试愉快！

编辑：抱歉，实际上我已经尝试在给定的博客文章和来自shark 的非常简单的文档之间进行组合。
