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