Thanks for the great breakdown of the relevant work.

That isn't true. We are actively adding new features. However, there
is certainly a focus on doing MapReduce well rather than trying to
implement all potential distributed computation paradigms. I suspect
that the right solution is doing two levels like Mesos:
Where MapReduce is one framework running on the cluster. That way you
can keep the framework stable, support MapReduce well, and let other
users explore other idioms.
