-------------------------------------
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).
