             Summary: Stop-and-Start Upgrade: HDP 2.1->2.3 needs to stop services using 2.1, and start using 2.3.
                 Key: AMBARI-13052
                 URL: https://issues.apache.org/jira/browse/AMBARI-13052
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.0
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
             Fix For: 2.2.0


For a Stop-and-Start Upgrade from HDP 2.1 -> 2.3, we need to stop all services using the scripts for HDP 2.1, and then start them using HDP 2.3.

Today, during an Upgrade, we currently set the desired stack id when we process Upgrade Pack and insert the upgrade record. That means that all start/stop commands use the scripts from the desired stack.

Instead, we need a Server Side Action to be called right before we run "hdp-select set all" that will change the desired stack id to the new version; this will permit stopping on the old version, and starting on the new version.

When we downgrade, we commence the orchestration again, and we again call the Server Side Action to change the desired stack id, this time to the starting version.
