我正在尝试学习Apache Spark。我关注this book。我下载了Apache Spark 1.5.1并将其解压缩为F：\ spark-1.5.1。我用spark-shell开始了。我每次都会收到以下异常：

Spark Context工作正常。 SQLContext不是。我想知道设置/配置独立spark实例的正确方法是什么。

请阅读下面的评论，了解我为何创建此内容。

我不想在不知道自己在做什么的情况下尝试2-3次随意的事情。

我猜你正在讨论的随机事情是复制winutils.exe。那么这是因为Spark有时会在配置中查找HADOOP_HOME变量，所以要克服这个文件被复制的错误。

This博客可以帮助您设置火花。 HTH！

感谢。
