I always use heapster and wanna to replace heapster to metrics-server. The metrics-server source is https://github.com/kubernetes-incubator/metrics-server/tree/master/deploy/1.8%2B

I have read and tried searching in google, but it's unrelated with my logs error.

I expect kubectl top pod or kubectl top node is running very well. However, since i applied metrics-server, i cannot to execute those commands. In the meantime, i deleted metrics-server apiservice and everything is fine. But yeah, i am still using heapster.

Can someone help me to done this or enlight me.
