-------------------------------------------
Summary: NameNode HA Wizard: allow the user to exit out of the
wizard with a warning pointing to manual rollback steps
Key: AMBARI-3405
URL: https://issues.apache.org/jira/browse/AMBARI-3405
Project: Ambari
Issue Type: Task
Components: client
Affects Versions: 1.4.1
Reporter: Antonenko Alexander
Assignee: Antonenko Alexander
Fix For: 1.4.1
1) Add "X" on all pages in the "Enable HA" wizard
2) Remove the "Rollback" button
3) Up until (and including) the "Create Checkpoint" page, clicking on the X
just dismisses the wizard (as it does today)
4) If the user has started the "Configure Components" stage in the wizard
(which means: Ambari has failed after actually performing changes), when the
user clicks the X, the user will be warned with the following message:
* You are in the process of enabling NameNode HA. If you exit now, you *must*
follow manual instructions to revert back to the non-HA setup: \[link to doc -
target="_blank"\]. Are you sure you want to exit the wizard?
