We have a similar use-case for expressing resources as percentages. The cluster
has auto-scaling enabled but the queue quotas are capped to a max value. Child
template on the queue is configured to give every child queue some guarantees
and can have max configs to cap its usage. This is better expressed as a
percentage of the parent queue. To be more specific, this is the queue config
{noformat}
queues:
- name: root
submitacl: '*'
queues:
- name: queue
submitacl: '*'
maxapplications: 50
resources:
max:
{memory: 31450G, vcore: 4080}
childtemplate:
maxapplications: 10%
resources:
guaranteed:
{memory: 10%, vcore: 10%}

> Project: Apache YuniKorn
> Issue Type: New Feature
> Components: core - scheduler
> Reporter: Rainie Li
> Assignee: Rainie Li
> Priority: Major
>
> Currently we need to set queue with guaranteed resources.
> example:
> {code:java}
> queues:
> - name: root
> submitacl: '*'
> queues:
> - name: queue1
> submitacl: '*'
> maxapplications: 12
> resources:
> guaranteed:
> {memory: 6290G, vcore: 816}
> max:
> {memory: 31450G, vcore: 4080}
> {code}
> It will be convenient to support percentage, so that we can configure queue
> without calculating the actual number.
