> Key: YUNIKORN-1559
> URL: https://issues.apache.org/jira/browse/YUNIKORN-1559
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: core - scheduler, shim - kubernetes
> Reporter: Wilfred Spiegelenburg
> Assignee: Qi Zhu
> Priority: Major
> Fix For: 1.3.0

>
> The best effort pods on K8s do not request resources. The default scheduler
> will just dump them on a node and hope for the best.
> In YuniKorn we need resources to schedule a pod. We reject a pod without a
> request set. As a default we assign 1M memory to the pod to make sure it gets
> scheduled. 1 byte would be better, need to rethink how we do this.
> This also affects other BestEffort pod resource calculations
> * init containers
> * pod overhead
