> 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
>
> Attachments: AMBARI-21999.patch

>
> 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...
