Klaus Ma commented on MESOS-3765:
---------------------------------
But how to define the "allocation chunk"? For example, two framework(f1 and
f2), each of them have a task acquire 1 CPU; one slave with only 1 CPU. I think
we need a way to let allocator know the minimal resource requirement: by
{{requestResources()}} or by {{filter}}. The framework can NOT define the
resource requirement ahead because it dependent on the pending workload in it.

> Project: Mesos
> Issue Type: Improvement
> Components: allocation
> Reporter: Alexander Rukletsov
>
> The built-in allocator performs "coarse-grained" allocation, meaning that it
> always allocates the entire remaining agent resources to a single framework.
> This may heavily impact allocation fairness in some cases, for example in
> presence of numerous greedy frameworks and a small number of powerful agents.
> A possible solution would be to allow operators explicitly specify
> granularity via allocator flags. While this can be tricky for non-standard
> resources, it's pretty straightforward for {{cpus}} and {{mem}}.
