I have a 2 node kubernetes cluster with calico networking. All the pods are up and running.

NAMESPACE     NAME                                       READY     STATUS    RESTARTS   AGE

I wanted to query calico-etcd using etcdctl, but I get the following error.

# etcdctl --debug --endpoints "http://10.142.137.11:6666" get calico
start to sync cluster using endpoints(http://10.142.137.11:6666)

Error:  100: Key not found (/calico) [4]

Any pointers on why I get this error?
