----------------------------------
Summary: ConfigureAction Must Take Into Account Stack Versions
Key: AMBARI-10739
URL: https://issues.apache.org/jira/browse/AMBARI-10739
Project: Ambari
Issue Type: Task
Components: ambari-server
Reporter: Nate Cole
Assignee: Nate Cole
Fix For: 2.1.0
The {{ConfigureAction}} that is used in the rolling upgrade process blindly
creates new configurations for every single change that is listed in the
upgrade pack. This needs to change in two fundamental ways:
- When upgrading or downgrading within a stack version (hdp-2.2.x.x to
hdp-2.2.y.y), before making a new configuration with the value from the upgrade
pack, compare the value to the current value. If they are the same, do no work
- When upgrading across stack versions (hdp-2.2 to hdp-2.3), new configurations
are already being created. There is no need to create new configurations since
the upgrade has already done this. The desired configurations should simply be
modified with the new values.
