-------------------------------------
Fix Version/s: 2.1.2
> Upgrade Orchestration To Skip Unhealthy Hosts
> ---------------------------------------------
>
> Key: AMBARI-12924
> URL: https://issues.apache.org/jira/browse/AMBARI-12924
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.0
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 2.2.0, 2.1.2
>
>
> When creating the various stages and tasks during the initial upgrade
> orchestration, hosts that are unhealthy will be skipped entirely. Components
> and clients on these hosts will not be a part of the upgrade, regardless of
> whether they contain slave or client components. If, during the course up the
> upgrade, a host is taken out of maintenance mode, it will not be inserted
> into the existing orchestration.
> The upgrade packs can also define the hosts that a specific execution task
> can be scheduled to run on. This type of dynamic host role command creation
> is only done at the time an upgrade orchestration is schedule. For tasks that
> are schedule to run on "all" hosts, the hosts that are schedule should also
> not contain those which are in maintenance mode.
