Bug 1317835

Description of problem:
Create a route and try to update the host for route by oc edit route, but the change doesn't take effect after save and quit the edit, and no warning information show up


Version-Release number of selected component (if applicable):
oc v3.2.0.3
kubernetes v1.2.0-origin-41-g91d3e75


How reproducible:
Always


Steps to Reproduce:
1. Create pod/service/route
# oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/nginx-pod.json
# oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/routing/unsecure/service_unsecure.json
# oc create route edge myroute --service=hello-nginx --hostname=www.edge.com
# oc get route
NAME      HOST/PORT      PATH      SERVICE            TERMINATION   LABELS
myroute   www.edge.com             hello-nginx:http   edge          name=hello-nginx

2. Try to update the host for route, eg change www.edge.com to www.edge1.com
# oc edit route myroute
 
3. Check the route


Actual results:
The change for route doesn't take effect
step3: The route is still same
# oc get route
NAME      HOST/PORT      PATH      SERVICE            TERMINATION   LABELS
myroute   www.edge.com             hello-nginx:http   edge          name=hello-nginx



Expected results:
The host could be updated successfully. If the host is not allowed to change, at least some friendly warnings show up
