Aleksandr Kovalenko created AMBARI-23576:

             Summary: Modify federation wizard steps to Stop All services and 
Start ZK and JN
                 Key: AMBARI-23576
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.7.0
            Reporter: Aleksandr Kovalenko
            Assignee: Aleksandr Kovalenko
             Fix For: 2.7.0

Restart JN with services up and running is not a good idea and can result in 
potential data loss.
Since we do not have server side ability to Stop All except ZK, here is new 
steps needed:

- Stop All Services
- Reconfigure
- Install NN
- Install ZKFC
- Start ZK
- Start JN
