Review request for Ambari, Alejandro Fernandez and Nate Cole.
Bugs: AMBARI-12924
https://issues.apache.org/jira/browse/AMBARI-12924
Repository: ambari
Description
-------
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.
