We have a full cluster running in production and suddenly it stopped working with the following error:

The Deployment "authapi" is invalid: metadata.finalizers[0]: Invalid value: "foregroundDeletion": name is neither a standard finalizer name nor is it fully qualified

My current cluster version is:

Client Version: version.Info{Major:"1", Minor:"7", GitVersion:"v1.7.3", GitCommit:"2c2fe6e8278a5db2d15a013987b53968c743f2a1", GitTreeState:"clean", BuildDate:"2017-08-03T07:00:21Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.6", GitCommit:"7fa1c1756d8bc963f1a389f4a6937dc71f08ada2", GitTreeState:"clean", BuildDate:"2017-06-16T18:21:54Z", GoVersion:"go1.7.6", Compiler:"gc", Platform:"linux/amd64"}

On the other hand, we cannot deploy either. The following message appear when kubectl is trying to deploy:

W1127 15:28:32.999978 42625 factory_object_mapping.go:423] Failed to download OpenAPI (the server could not find the requested resource), falling back to swagger
The Deployment "authapi" is invalid: metadata.finalizers[0]: Invalid value: "foregroundDeletion": name is neither a standard finalizer name nor is it fully qualified
/home/builduser/myagent/_work/_temp/kubectlTask/1511796511792/kubectl failed with return code: 1

Any help on this?
