----------------------------------------
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...
