Adam B updated MESOS-3765:
--------------------------
Comment: was deleted
(was: The IRC discussion with Adam Avilla turned out to be unrelated to this
ticket. He needed a way to exclude resources from Mesos' allocations, which is
solved by not including them in `--resources` if the tasks are run outside of
Mesos, and can be solved by reservations for tasks run by Mesos.)

> URL: https://issues.apache.org/jira/browse/MESOS-3765
> 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}}.
