> Key: YUNIKORN-790
> URL: https://issues.apache.org/jira/browse/YUNIKORN-790
> Project: Apache YuniKorn
> Issue Type: New Feature
> Components: core - scheduler
> Reporter: Wilfred Spiegelenburg
> Assignee: Rainie Li
> Priority: Major
> Labels: pull-request-available
>
> Queues have an option to set the MaxApplications that can run in a queue. There is currently no code in the scheduler that checks this setting.
> As a new feature we should add the enforcement for this setting:
> * enforce the setting on a leaf queue
> * enforce the setting on a parent, the apps running in a parent queue is defined as the sum of all the apps running in all leaf queues of the parent.
> As a side note from a config check: we need to make sure that the parent setting cannot be lower than any of the child queues it has. We _must not_ enforce that the parent setting must be larger than sum of all leafs.
