为什么火花壳失败，“此时出乎意料”？ [英] Why does spark-shell fail with "was unexpected at this time"?

问题描述

运行spark-shell命令时，我收到以下错误：

I am getting following error when running spark-shell command:

我已经从 http://spark.apache.org/downloads.html ，解压缩tar文件，将文件夹的内容粘贴到c：\Spark目录中。之后，我已经相应地配置了spark和jdk的环境变量，但是我收到这个错误。任何帮助将不胜感激。

I have downloaded spark-2.1.1-bin-hadoop2.7.tgz file from http://spark.apache.org/downloads.html, extracted the tar file and pasted the contents of the folder into c:\Spark directory. After that I have configured the environment variable for spark and jdk accordingly, but I am getting this error. Any help will be appreciated.

推荐答案

我几乎确保您的 JAVA_HOME 环境变量包含一个打破 spark-shell 的空格。请重新安装Java到路径中没有空格的目录。

I'm almost sure that your JAVA_HOME environment variable contains a space that breaks spark-shell. Please re-install Java to a directory with no spaces in the path.

您可以看到相关的代码段 bin / spark-class2.cmd spark-shell 在Windows下执行封面（通过 bin / spark-submit2.cmd shell脚本）：

You can see the relevant piece of code in bin/spark-class2.cmd that spark-shell executes on Windows under the covers (through bin/spark-submit2.cmd shell script):

if "x%1"=="x" (

所以当 spark-class2.cmd 将％1 替换为具有空格（或类似东西）的路径，最终为：

So when spark-class2.cmd substitutes %1 to a path with a space (or something similar) it ends up as:

if "x"Files\Java\jdk1.8.0_45""=="x" (

由于太多的双引号而导致错误。

that gives the error due to too many double quotes.

神秘的是如何在这个地方， JAVA_HOME 似乎找不到原因，但这是w帽子我们在这里看到。

The mystery is how does the JAVA_HOME end up in this place. I can't seem to find the reason, but that's what we see here.
