UpdateStatus() for custom resources not working

[diptadas]

/kind bug
/sig api-machinery
@kubernetes/sig-api-machinery-bugs

What happened:
My custom resource type has a status field. I have generated client for it using genclient.
Here is the defination of my CRD type:

// +genclient
// +k8s:openapi-gen=true
// +k8s:deepcopy-gen:interfaces=k8s.io/apimachinery/pkg/runtime.Object

type Recovery struct {
	metav1.TypeMeta   `json:",inline,omitempty"`
	metav1.ObjectMeta `json:"metadata,omitempty"`
	Spec              RecoverySpec   `json:"spec,omitempty"`
	Status            RecoveryStatus `json:"status,omitempty"`
}

The generated UpdateStatus() function:

// UpdateStatus was generated because the type contains a Status member.
// Add a +genclient:noStatus comment above the type to avoid generating UpdateStatus().

func (c *recoveries) UpdateStatus(recovery *v1alpha1.Recovery) (result *v1alpha1.Recovery, err error) {
	result = &v1alpha1.Recovery{}
	err = c.client.Put().
		Namespace(c.ns).
		Resource("recoveries").
		Name(recovery.Name).
		SubResource("status").
		Body(recovery).
		Do().
		Into(result)
	return
}

Now when I call UpdateStatus() for a Recovery object (stash-mduabx) it gives following error:

the server could not find the requested resource (put recoveries.stash.appscode.com stash-mduabx)

And the log of api call:

PUT https://192.168.99.100:8443/apis/stash.appscode.com/v1alpha1/namespaces/test-stash/recoveries/stash-mduabx/status 404 Not Found in 11 milliseconds

What you expected to happen:
It should update the status field.

How to reproduce it:
Define a CRD type with status field and generate client for it using genclient. Create a object of that type using kubectl. Now get the object from go program and call UpdateStatus() for the object.

Environment:

• Kubernetes version: 1.7.5

The client generates a status method because there is a status field, but that does not mean the server has support for that method.

kubernetes/community#913 is a proposal to add server support for status subresources for CRD objects.
