I verified that this occurs when you use different versions of go on the client vs. server.

$ kubectl version

client with go1.8.1 works with server with go1.8.3

it seems that client with go1.8.3 doesn't work with server with go1.8.1

@timothysc Is this a blocking issue for 1.7?

I think it's a bad experience, but I don't know if it's blocker worthy. I'd definitely cherry-pick any fixes.

I'm seeing this same issue with a build of hyperkube.. so in this case the server and client are the same binary, so they can't be using different versions:

I originally saw it on the delta in behavior from two different generated versions, which could be a false positive.

same output with gcr.io/google_containers/hyperkube-amd64:v1.7.5 image.

Was wondering why one of my cron pods who's using this image for kubectl kept outputting

It's fixed from Kubernetes 1.8 and onward. Update to get rid of it

A cherry-picked backport to 1.7 is in the pipeline: kubernetes/kubernetes#53950
