> I'm running a local dev env *make run_plugin* based on 1.2.0, no admission
> controller is configured. Additionally, I configured a configmap in the
> default namespace:
> {code:bash}
> apiVersion: v1
> data:
> queues.yaml: |
> partitions:
> - name: default
> nodesortpolicy:
> type: binpacking
> queues:
> - name: root
> submitacl: '*'
> queues:
> - name: app1
> submitacl: '*'
> properties:
> application.sort.policy: fifo
> resources:
> max:
> {memory: 200G, vcore: 1}
> kind: ConfigMap
> metadata:
> name: yunikorn-configs
> {code}
> Then I create a Pod with the following config:
> {code:bash}
> kind: Pod
> apiVersion: v1
> metadata:
> name: pod-1
> labels:
> applicationId: "app1"
> spec:
> schedulerName: yunikorn
> containers:
> - name: pause
> image: registry.k8s.io/pause:3.6
> resources:
> requests:
> cpu: 1
> {code}
> The pod cannot be scheduled with a status {*}ApplicationRejected{*}, and I
> observed log in the shim as:
