You're totally right about the current problem with inheritance when having
multiple dimensions (job vs. session, yarn vs. standalone. vs Mesos). I've
looked at the link you've posted and it looks really interesting. Once we have
ditched Java 7 support, we can change the code to use this technique in order
to reduce code duplication.
