             Summary: Allow The Removal Of Hosts in Maintenance Mode Via The Web Client During An Upgrade
                 Key: AMBARI-13600
                 URL: https://issues.apache.org/jira/browse/AMBARI-13600
             Project: Ambari
          Issue Type: Task
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
            Priority: Critical
             Fix For: 2.1.3


During an upgrade, web client allow for a host to be placed into Maintenance Mode in order for it to be excluded from the upgrade. Although there is work planned to be able to finalize an upgrade with hosts that are in MM and out-of-sync, in the short term there also needs to be the ability to remove these hosts so that finalization can complete.
The web client should expose the ability to remove hosts in MM during an upgrade. This should only apply to hosts in MM. It can be made a part of the RU wizard at the time of finalization or exposed in other areas of the UI.
