Deploy customized kube-scheduler

Question

I deploy kube-scheduler using https://kubernetes.io/docs/tasks/administer-cluster/configure-multiple-schedulers/ .

I followed the steps exactly at the beginning however it does not schedule the node using "my-scheduler" the node is pending instead.

The log of "my-scheduler" pod is

It seems it does not have permission to access resources. I tried configured RBAC as the link says but it does not help.

Please help me if you ever tried this.
