----------------------------------

             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.
