刚刚在我的arch linux中安装了Apache Spark 2.2.0-4，以及Scala 2.12.4和Apache Hadoop 3.0，我执行spark-shell后面临以下异常。

检查Spark Shell "Failed to Initialize Compiler" Error on a mac后，我尝试使用jdk 8，但此解决方案对我不起作用。

你能否说一下它还能做些什么呢？

TL; DR Spark支持Java 8（并且不支持Java 9）。

引发 2.3.0-SNAPSHOT （今天由master构建）支持Java 8。

使用{9}中的Java 9，您将获得您所面临的例外情况。

由于OP位于Arch Linux上并安装了Apache Spark package from AUR， Sources 部分显示了为Linux发行版自定义的7个文件，包括： spark-env.sh

JAVA_HOME

无论export JAVA_HOME=/usr/lib/jvm/default-runtime 使用的PATH环境变量如何，都可以选择Java 9。

PROTIP 您可以使用spark-shell环境变量来了解SPARK_PRINT_LAUNCH_COMMAND开头的命令和Java，例如spark-shell。您还可以查看SPARK_PRINT_LAUNCH_COMMAND=1 spark-shell更多Linux调试shell脚本的方式（如sh -x spark-shell）。

一个解决方案是将spark-shell配置为默认使用Java 8（而不是Java 9），但那......嗯......你的家庭练习。 Happy Spark'ing！

答案 1 :(得分：3)

只是为了澄清问题，正如你在第二次编辑中看到的那样，spark正在使用java 9。 spark-env.sh 将JAVA_HOME设置为：

export JAVA_HOME=/usr/lib/jvm/default-runtime

要在arch linux中设置默认jdk，请检查文件夹 / usr / lib / jvm 以查看不同的jvm发行版。

将分配标记为默认值：

archlinux-java set java-8-jdk
