java.io.IOException：无法在Hadoop二进制文件中找到可执行文件null\bin\winutils.exe。在Windows 7上启动Eclipse

问题描述

我无法在 Scala IDE （Maven spark project）中安装一个简单的 spark Windows 7

I'm not able to run a simple spark job in Scala IDE (Maven spark project) installed on Windows 7

添加了Spark核心依赖关系。

Spark core dependency has been added.

val conf = new SparkConf().setAppName("DemoDF").setMaster("local")
val sc = new SparkContext(conf)
val logData = sc.textFile("File.txt")
logData.count()

错误：

推荐答案

是解决您的问题的一个很好的解释。

Here is a good explanation of your problem with the solution.

1. 从。



2. SetUp您的HADOOP_HOME环境变量在操作系统级别或以编程方式：

1. Download winutils.exe from http://public-repo-1.hortonworks.com/hdp-win-alpha/winutils.exe.

2. SetUp your HADOOP_HOME environment variable on the OS level or programmatically:

System.setProperty（hadoop.home.dir，具有winutils的bin文件夹的完整路径）;

System.setProperty("hadoop.home.dir", "full path to the bin folder with winutils");
