Thanks Jay,

I checked the kubelet log. There are a lot of Watch closed error like
below. Here is the full log http://fpaste.org/188964/46261561/ .

*Status:"Failure", Message:"unexpected end of JSON input", Reason:""*
*Status:"Failure", Message:"501: All the given peers are not reachable*

Please note that my environment was setup by following the quickstart
guide. It seems that all the kube components were running (checked by using
systemctl status command), and all nodes can ping each other. Any further
suggestion?

Thanks,
Hongbin
