在 Windows 上启动火花

Question

我正在尝试学习 Apache Spark。我关注this book。我下载了 Apache Spark 1.5.1 并将其提取到 F:\spark-1.5.1。我从 spark-shell 开始。我每次都会遇到以下异常：

15/11/06 15:29:06 WARN Connection: BoneCP specified but not present in CLASSPATH
 (or one of dependencies)

Spark 上下文工作正常。 SQLContext 不是。我想知道设置/配置独立火花实例的正确方法是什么。

请阅读我在下面的评论以了解我创建此内容的原因。

Answer 1

我不想在不知道自己在做什么的情况下尝试 2-3 次随机的事情。

我猜你说的随机的事情是复制 winutils.exe。那是因为 Spark 有时会在配置中查找 HADOOP_HOME 变量，所以为了克服这个错误，正在复制文件。

This博客可以帮助你设置火花。 HTH！

谢谢。
