Subject [jira] [Created] (AURORA-1384) Provide alternate policies for offer assignment to tasks

Anindya Sinha created AURORA-1384:
-------------------------------------

             Summary: Provide alternate policies for offer assignment to tasks
                 Key: AURORA-1384
                 URL: https://issues.apache.org/jira/browse/AURORA-1384
             Project: Aurora
          Issue Type: Story
          Components: Scheduler
    Affects Versions: 0.8.0
            Reporter: Anindya Sinha


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).
