Give use cases to understand the features better about fenzo

[spodila]

Fenzo caters to the needs of a Mesos framework for advanced scheduling optimizations and cluster autoscaling, see this blog for an overview.

What you are describing seems to be a case of multiple frameworks in a Mesos cluster, where one or more of them can starve for resources if another framework hoards (or has used up) all of the offers. That may require a solution in Mesos itself (just as an example, some way of fair sharing plus preemptions). Or, a single Spark framework may be able to achieve such fair share among its various Spark jobs instead of having one framework per job. Although, I am not as knowledgeable about Spark framework to say how feasible that is. Fenzo can be useful for such a framework in terms of optimizing task placements. However, preemptions and fair share concepts are not available in Fenzo yet.

Ok, thanks. Exactly what I needed to hear.
