Joining a node to the cluster using kubeadm join

Hi, I am running a 2 node cluster which is running Container Linux. Tried to install k8s in master first using kubeadm, it succeeded. Now trying to join the second node as a worker to the master using kubeadm join. The returned result says that the node attachment is successful, whereas in the master node the pods named kube-apiserver, kube-scheduler, kube-controller-manager and etcd goes to pending state. Any ideas on how to debug this ? I don’t see any errors in kubectl get events as well.
