Question

我正在尝试在Windows 10上安装Spark 1.6.1，到目前为止我已经完成了以下操作......

下载spark 1.6.1，解压缩到某个目录，然后设置SPARK_HOME
下载scala 2.11.8，解压缩到某个目录，然后设置SCALA_HOME
设置_JAVA_OPTION env变量
只需下载zip目录，然后设置HADOOP_HOME env变量，即可从https://github.com/steveloughran/winutils.git下载winutils。（不确定这是不正确的，由于权限被拒绝，我无法克隆目录。）

当我去火花回家并运行bin \ spark-shell时，我得到了

'C:\Program' is not recognized as an internal or external command, operable program or batch file.

我必须遗漏一些东西，我不知道如何从windows环境中运行bash脚本。但希望我不需要理解只是为了让这个工作。我一直在关注这个人的教程 - https://hernandezpaul.wordpress.com/2016/01/24/apache-spark-installation-on-windows-10/。任何帮助，将不胜感激。

您需要下载winutils可执行文件，而不是源代码。

您可以下载here，或者如果您真的想要整个Hadoop发行版，可以找到2.6.0二进制文件here。然后，您需要将HADOOP_HOME设置为包含winutils.exe的目录。

此外，确保您放置Spark的目录是一个不包含空格的目录，这非常重要，否则它将无效。

设置完成后，您无法启动spark-shell.sh，启动spark-shell.cmd：

C:\Spark\bin>spark-shell

Answer 2

在Windows上，您需要明确指定放置hadoop二进制文件的位置。

以下是设置spark-scala独立应用程序的步骤。

下载winutil.exe并将其放置在bin文件夹下的某个文件夹/目录中，例如c：\ hadoop \ bin

完整路径类似于c：\ hadoop \ bin \ winutil.exe

现在在创建sparkSession时，我们需要指定此路径。请参考下面的代码段：

包com.test.config

 import org.apache.spark.sql.SparkSession

 object Spark2Config extends Serializable{
            System.setProperty("hadoop.home.dir", "C:\\hadoop")
            val spark = SparkSession.builder().appName("app_name").master("local").getOrCreate()       
 }

winutils spark windows安装env_variable
