>             Project: Aurora
>          Issue Type: Story
>          Components: Scheduler

> Currently, offers are arranged in a list. When new tasks need to be assigned an offer,
the first offer from the list that matches the task constraints is assigned which over time
may result in a non even distribution of tasks on slaves in the cluster.
> In addition to existing algorithm ("first-fit"), we can support alternate algorithms
as follows:
> i) bin-packed: Offer is assigned to a task based on a bin packed algorithm which ensures
a specific offer is used up to the maximum possible with respect to resources (cpu) before
moving to an alternate offer.
> ii) even-distribution: Offer is assigned to ensure even distribution of load on each
slave on the cluster based on resources (cpu).
