Bug 1386401

Description of problem:

I am trying to edit a project's annotation, namely "openshift.io/node-selector". 

If I do "oc edit project openshift-infra" and change the "openshift.io/node-selector" to "type=infra", and save it gives me the following error:

 Invalid value: "": field is immutable, try updating the namespace

If I try oc annotate, the same thing happens:

[root@ip-172-31-56-156 ~]# oc annotate project openshift-infra openshift.io/node-selector=type=infra --overwrite
The Project "openshift-infra" is invalid.
metadata.annotations[openshift.io/node-selector]: Invalid value: "type=infra": field is immutable, try updating the namespace
[root@ip-172-31-56-156 ~]#


Now, if I use "namespace" instead of "project" things work as expected.

oc edit namespace openshift-infra

OR

[root@ip-172-31-56-156 ~]# oc annotate namespace openshift-infra openshift.io/node-selector=type=infra --overwrite
namespace "openshift-infra" annotated

Things work as expected.


Version-Release number of selected component (if applicable):

I have seen this in 3.2.1.15 and 3.3.0.32


How reproducible:

Very

Steps to Reproduce:
1.  Install Openshift cluster
2.  oc edit project openshift-infra
3.  change/update the openshift.io/node-selector
4.  attempt to save

Actual results:

Error on saving. 

Expected results:

I would expect it to save the annotation as requested.

Additional info:

I don't understand why this works in ns and not project.  What is the difference?  If there a reason it works with one but not the other?
