Description

Run incorrect command such as:
/usr/bin/yarn org.apache.hadoop.yarn.applications.distributedshell.Client -jar <distributedshell jar> -shell_command ./test1.sh -shell_script ./

would show shell exit code exception with no useful message. It should print out sysout/syserr of containers/AM of why it is failing.
