Question

我愿意在与我的版本（java 11）不兼容的机器上运行Spark shell，因此需要删除并安装兼容的版本（jdk8）。运行oracle指定的以下命令：

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin 
sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane 
sudo rm -fr ~/Library/Application\ Support/Oracle/Java

命令运行，但仍然存在Java 11：

$ java -version
java version "11" 2018-09-25
Java(TM) SE Runtime Environment 18.9 (build 11+28)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11+28, mixed mode)

不确定是什么原因造成的。

这不会删除JRE或JDK。如果需要查找所有Java安装，只需启动以下命令：

$ /usr/libexec/java_home -V
