Description
/kind bug
What happened:
I tried to delete a namespace via https://github.com/kubernetes-client/java and was hit by a gnarly error when the lib tried to deserialize the returned body
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 321 path $.status
So I dug into the API repsonses and found out that indeed something appears to be wrong in the swagger spec + official API documentation. According to DELETE namespace docs the response should be a Status v1 meta object. However, the returned response looks actually like this:
12:24 $ kubectl --v 8 delete namespace aafs-dxbd85

I1018 12:26:16.924643 10111 request.go:874] Response Body: {"kind":"Namespace","apiVersion":"v1","metadata":{"name":"aafs-dxbd85","selfLink":"/api/v1/namespaces/aafs-dxbd85","uid":"19326fb3-d2bd-11e8-97ef-fa163e607805","resourceVersion":"77243","creationTimestamp":"2018-10-18T10:03:44Z","deletionTimestamp":"2018-10-18T10:26:16Z"},"spec":{"finalizers":["kubernetes"]},"status":{"phase":"Terminating"}}
The status field should be a string of either "Success" or "Failure" according to docs + swagger spec, but it's actually an object status":{"phase":"Terminating"}.
What you expected to happen:
The status field should be a string.
How to reproduce it (as minimally and precisely as possible):
Create a namespace, delete it, observe status field content in output
kubectl create namespace aafs-dxbd85
kubectl --v 8 delete namespace aafs-dxbd85
Anything else we need to know?:
Environment:
- Kubernetes version (use
