Spark Shell“无法初始化编译器"在Mac上发生错误 [英] Spark Shell "Failed to Initialize Compiler" Error on a mac

问题描述

我刚刚在新机器上安装了spark，并使用自制软件安装了Java，Scala和Apache-spark之后得到了以下错误.安装过程如下:

I just installed spark on my new machine and get the following error after installing Java, Scala and Apache-spark using homebrew. The install process is given below:

$ brew cask install java
$ brew install scala
$ brew install apache-spark

安装后，当我尝试使用spark-shell运行基本示例时，出现以下错误.任何帮助都将不胜感激.

Once installed, when I try to run a basic example using spark-shell, i get the following error. Any help greatly appreciated.

$ spark-shell
 Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

** Note that as of 2.8 scala does not assume use of the java classpath.
** For the old behavior pass -usejavacp to scala, or if using a Settings

推荐答案

Spark与Java 9不兼容，Java 9是brew cask install java的最新版本.如果您确实安装了Java 9，则需要安装Java 8:

Spark is incompatible with Java 9, which is the version brew cask install java will install if it is up to date. If you did install Java 9, what you need to do is install Java 8 instead:

brew cask uninstall java
brew tap caskroom/versions
brew cask search java
brew cask install java8
