------------------------------------
Hi [~wfps1210], I patched your initial PR
[https://github.com/apache/yunikorn-core/pull/384] and updated a little bit
because our team has an urgent need to use MaxApplication feature.
Are you actively working on it? If so, I will abandon my PR
[https://github.com/apache/yunikorn-core/pull/429]
Feel free to check out comments on my PR.
> Implement MaxApplications enforcement
> -------------------------------------
>
> 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
> 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.
