Klaus Ma commented on MESOS-3765:
---------------------------------
For [~gyliu]'s proposal on {{requestResources}}, I think that would be a long
term solution for us; maybe we can re-visit it in "allocator refactor" ticket.
[~alexr], for the "granularity", suggest to make the default value to be
{{total resource/framework #}} of each resources. But one concern is if lots of
frameworks, the allocator's performance will be downgrade. Maybe we can have a
try to see the performance. Any comments.

> 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}}.
