Oozie vs. YARN "application"
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?
