/bin/bash: /bin/java: No such file or directory error in Yarn apps in MacOS

在 stackoverflow 找到的方案
In HADOOP_HOME/libexec/hadoop-config.sh look for the if condition below # Attempt to set JAVA_HOME if it is not set

Remove extra parentheses in the export JAVA_HOME lines as below. Change this

if [ -x /usr/libexec/java_home ]; then
    export JAVA_HOME=($(/usr/libexec/java_home))
else
    export JAVA_HOME=(/Library/Java/Home)
fi

to

if [ -x /usr/libexec/java_home ]; then
    // note that the extra parentheses are removed
    export JAVA_HOME=$(/usr/libexec/java_home)
else
    export JAVA_HOME=/Library/Java/Home
fi

然后重启yarn

但我用的是版本时 3.2.2
hadoop-config.sh 脚本重构过，在以下三个方法中，没找到上面要改的地方。所以直接在后面追加 JAVA_HOME。 然后重启yarn, 亲测可用
