[Dmitry Mescheryakov <dmescheryakov@xxxxxxxxxxxx>]

Let me explain my position on that matter.

Savanna is an OpenStack service dedicated to provisioning Hadoop clusters.
Taking into account Amazon Cloud Formation approach, it makes sense to
expose Savanna as one of Heat resources. Just like Amazon exposes its
services as CF resources.

We could also use Heat inside Savanna to perform the actual provisioning.
But the thing is that the provisioning operations Savanna does right now
are rather trivial. Using Heat will make it more complex without adding
significant value. Certainly this might change in the future, but we do not
consider to use Heat in the current phase.

Sure we can discuss this during Savanna presentation which will take place
in Unconference room on Monday at 11:50.

Absolutely. The main difference is that Savanna is the Hadoop oriented
service.
It aims to provide unified user-friendly API that will allow users to
deploy Hadoop clusters fastly and without additional configurations for
cluster provisioning.
