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