[jira] [Created] (AMBARI-21999) Always Take Target Read-Only Properties On Stack Upgrade

Jonathan Hurley created AMBARI-21999:
----------------------------------------

             Summary: Always Take Target Read-Only Properties On Stack Upgrade
                 Key: AMBARI-21999
                 URL: https://issues.apache.org/jira/browse/AMBARI-21999
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 2.5.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
            Priority: Critical
             Fix For: 2.6.0


STR:
- Install a stack, such as HDP 2.3
- Modify the {{cluster-env/stack_features}} structure
- Upgrade to HDP 2.6

The auto-merge which happens can't properly merge {{cluster-env/stack_features}} since it has deviated from the stock values of HDP 2.3. This is dangerous since this is needed for proper operation.

Because it's defined as a read-only value, we should be able to detect this in the auto-merge fro the upgrade and force it to the new stack's default value...
