Question

我是使用python编程的初学者，我想在OS X上安装spark，以便我可以使用它的库。

我在终端上写了这个命令来安装spark：

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

但是，一旦我输入spark-shell，我就会得到这个huuge消息：

MacBook-de-Guillermo-Romero:~ Guillermo$ 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).

Failed to initialize compiler: object java.lang.Object in compiler mirror not found.
** 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
** object programmatically, settings.usejavacp.value = true.

任何人都知道哪个是问题？

Answer 1

Spark与Java 9不兼容，如果它是最新版本，则会安装brew cask install java版本。如果你确实安装了Java 9，那么你需要做的就是安装Java 8：

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

请注意，这似乎与this question重复，上面是answer I provided there的精确副本。我相信，有更多声誉的人应该举报这一点。
