Hadoop 0.23 (MRv2 or YARN) provides the concept of an "application", which is described as
either a classic single MR job *or* a DAG of such jobs...which at a glance appears redundant
with Oozie's primary purpose.
How do they differ? Does 0.23 effectively obviate the service that Oozie provides or is Oozie
more powerful than a YARN "application"...or simply more different from an application than
I have conceptualized to the point that they don't necessarily step on one another's toes?
