解決方法：
查看ClusterRole: system:heapster的權限，發現的確沒有針對Resource: nodes/stats 的create權限
#kubectl describe clusterrole system:heapster
生成清單文件
#kubectl get clusterrole system:heapster -o yaml > heapster_modify.yaml
#kubectl delete -f heapster_modify.yaml
#kubectl apply -f heapster_modify.yaml
#kubectl delete -f heapster.yaml
#kubectl apply -f heapster.yaml
