我刚刚开始研究apache spark。我做的第一件事是尝试在我的机器上安装 spark。我使用 hadoop 2.6 下载了预构建的 spark 1.5.2。当我运行 spark shell 时出现以下错误

我搜索了这个错误，发现我必须下载 winutils.exe，我设置了路径 HADOOP_HOME = "c:\Hadoop" 然后运行命令

C:\Hadoop\bin\winutils.exe chmod 777 /tmp/hive

但是我得到了以下错误

This version of C:\Hadoop\bin\winutils.exe is not compatible with the version of
 Windows you're running. Check your computer's system information to see whether
 you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contac
t the software publisher.

我试图搜索 32 位版本的 winutils.exe，但我找不到它。请帮助我完成此安装。 提前谢谢你

最佳答案

以下链接可能会有帮助。

Not able to find winutils.exe for hadoop 2.6.0 for 32 bit windows

关于hadoop - 在 Windows 7 32 位上安装 Apache Spark，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34468464/
