Description

After upgrading from HDP 2.2 to HDP 2.3, the web client is using the wrong stack version when making requests to endpoints like validation and recommendations.

STR:
1) Install HDP 2.2 (ZooKeeper only is enough)
2) Perform Express Upgrade to HDP 2.3
3) Try to add a service, like Storm

Observe:

Remote Address:[::1]:8080
Request URL:http://localhost:8080/api/v1/stacks/HDP/versions/2.2/validations
Request Method:POST
Status Code:200 OK

and

Remote Address:[::1]:8080
Request URL:http://localhost:8080/api/v1/stacks/HDP/versions/2.2/recommendations
Request Method:POST
Status Code:200 OK

This causes invalid recommendations and configurations when adding services after upgrade. If the user logs out and then back in, the correct version is used.
