hadoop：/bin/bash: /bin/java: No such file or directory

Stack trace: ExitCodeException exitCode=127

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

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

Restart yarn after you have made this change.

More detailed info can be found here https://issues.apache.org/jira/browse/HADOOP-8717 and seems that Hadoop 3.0.0-alpha1 is the first release with the fix.
