spark-class: line 71...No such file or directory
提问by lengthy_preamble
I've installed Spark 2.1.1 on Ubuntu and no matter what I do, it doesn't seem to agree with the java path. When I run "spark-submit --version" or "spark-shell" I get the following error:
我已经在 Ubuntu 上安装了 Spark 2.1.1，无论我做什么，它似乎都不符合 java 路径。当我运行“spark-submit --version”或“spark-shell”时，出现以下错误：
/usr/local/spark/bin/spark-class: line 71: /usr/lib/jvm/java-8-openjdk-amd64/jre/bin//bin/java: No such file or directory
/usr/local/spark/bin/spark-class：第 71 行：/usr/lib/jvm/java-8-openjdk-amd64/jre/bin//bin/java：没有那个文件或目录
Now obviously the "/bin//bin/java" is problematic, but I'm not sure where to change the configuration. The spark-class file has the following lines:
现在显然“/bin//bin/java”有问题，但我不确定在哪里更改配置。spark-class 文件有以下几行：
if [ -n "${JAVA_HOME}" ]; then
RUNNER="${JAVA_HOME}/bin/java"
I was originally using a version of Spark meant for Hadoop 2.4 and when I changed it to "RUNNER="${JAVA_HOME}" it would either give me the error "[path] is a directory" or "[path] is not a directory." This was after also trying multiple path permutations in /etc/environment
我最初使用的是用于 Hadoop 2.4 的 Spark 版本，当我将其更改为“RUNNER="${JAVA_HOME}”时，它会给我错误“[path] is a directory”或“[path] is not a目录。”这是在 /etc/environment 中尝试多个路径排列之后
What I now have in /etc/environment is:
我现在在 /etc/environment 中有：
JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/"
JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/"
This is the current java setup that I have:
这是我当前的 Java 设置：
root@ubuntu:~# update-alternatives --config java There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
r oot@ubuntu:~# update-alternatives --config java 链接组 java 中只有一种选择（提供 /usr/bin/java）：/usr/lib/jvm/java-8-openjdk-amd64/jre/二进制/Java
bashrc has the following:
bashrc 具有以下内容：
export SPARK_HOME="/usr/local/spark"
export PATH="$PATH:$SPARK_HOME/bin"
Can anyone advise: 1) What files I need to change and 2) how I need to change them? Thanks in advance.
任何人都可以建议：1）我需要更改哪些文件以及 2）我需要如何更改它们？提前致谢。
spark-class file is in the link, just in case:
spark-class 文件在链接中，以防万一：

In the /etc/environment file replace
在 /etc/environment 文件中替换
JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/
with
和
JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre/
then execute
然后执行
source /etc/environment
also RUNNER="${JAVA_HOME}/bin/java"should be kept as it is
也RUNNER="${JAVA_HOME}/bin/java"应该保持原样

Windows Environment:
视窗环境：
Open Advanced system settings -> Environment Variablesto set JAVA_HOMEpath, and the most common mistake is setting the path to JAVA folder:
打开Advanced system settings -> Environment Variables设置JAVA_HOME路径，最常见的错误是设置了JAVA文件夹的路径：
JAVA_HOME: Directory-Name:\java
rather than setting it to JDK folder
而不是将其设置为 JDK 文件夹
JAVA_HOME: Directory-Name:\jdk
This is how it worked for me.
这就是它对我的工作方式。
