> I Simultaneously submit 4 gang apps to yunikorn，sometimes 4 apps get
> pending, while two pgs get running, that's not expected.
> It can be reproduced as follows：
> queues
> 1.kubectl create configmap yunikorn-configs --from-file=queues.yaml -n
> yunikorn
> * queues.yaml
> {code:java}
> partitions:
> - name: default
> queues:
> - name: root
> queues:
> - name: my-dev
> submitacl: "*"
> resources:
> guaranteed: { memory: 1G, vcore: 1 }
> max: { memory: 2G, vcore: 2 }{code}
> 2.Simultaneously submit gang-scheduling-job-example1-4.yaml, while
> gang-scheduling-job-example1-4.yaml only differ in name and applicationId
> {code:java}
> apiVersion: batch/v1
