When Oozie launcher(map only mapreduce job) gets scheduled to run on RHEL7 node in a mixed OS environment, it may get failed with below ERROR(stderr section of Oozie launcher logs):

log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

.

Why it failed?

This happens because "/bin" and "/sbin" missing in your $PATH in container launch environment.

$PATH variable gets derived from nodemanager's env and nodemanager get's the env from ambari-agent's /var/lib/ambari-agent/ambari-env.sh.

.

How to fix this?

To fix this, add "/bin" and "/sbin" in /var/lib/ambari-agent/ambari-env.sh, restart ambari-agent followed by nodemanager restart.

.

Note - It may get failed with "ln: command not found" error, please follow the same resolution mentioned above in this case as well.

.

Please comment if you have any feedback/questions/suggestions. Happy Hadooping!! :)
