>          Issue Type: Task
>          Components: client
>    Affects Versions: 1.4.2
>            Reporter: Aleksandr Kovalenko
>            Assignee: Aleksandr Kovalenko
>             Fix For: 1.4.2

> We need to allow user to quit the wizard with a warning popup. We don't want to be in
a situation where user is stuck due to any unforeseen JS error or due to a constant command/API
failure and has no possible way to quit the wizard. 
> Also with the inclusion of start services with smoke tests as part of the wizard, chances
of wizard failing will increase.
> As a solution we can document manual steps for completing or reverting reassign master
wizard as we have for NameNode HA wizard. When user tries to quit after Review page, we can
show a confirmation pop-up with a message: "Reassign <component name> wizard is in progress.
It's necessary to complete the wizard for Ambari to be in usable state. If you choose to quit,
you must follow manual instructions to complete or revert reassign <component name>
wizard as documented in the Ambari User Guide. Are you sure you want to exit the wizard ?".
