[Spark] Spark 安装配置

原文地址：https://www.cnblogs.com/memento/p/9148732.html

Windows 上的单机版安装

下载地址：http://spark.apache.org/downloads.html

本文以 Spark 2.3.0 为例

>>> 下载下来的文件是 tgz 格式的压缩文件，直接利用压缩软件将其打开，可以看见里面有一个 tar 格式的压缩文件，继续用压缩软件打开，最终如下图所示：

>>> 将其中的 spark-2.3.0-bin-hadoop2.7 文件夹解压，新增 SPARK_HOME 环境变量，设置为解压路径，并将其追加到 PATH 环境变量；

>>> 此时在 cmd 窗口中执行 "spark-shell" 命令可得到如下提示：

提示说在 hadoop 路径下无法定位到 winutils，所以接下来需要配置 Hadoop；

>>> 详见：Windows 下的 Hadoop 2.7.5 环境搭建

>>> 随后再重新执行 "spark-shell" 命令即可；
