--------------------------------------------
Summary: Make assignMasters controller more reusable and add
support of cardinality
Key: AMBARI-10404
URL: https://issues.apache.org/jira/browse/AMBARI-10404
Project: Ambari
Issue Type: Task
Components: ambari-web
Affects Versions: 2.1.0
Reporter: Aleksandr Kovalenko
Assignee: Aleksandr Kovalenko
Fix For: 2.1.0
{{wizardStep5Controllert}} is used in Install, Add Service, Move, NN HA, RM HA,
future Ranger Admin HA and Ranger KMS HA wizards. But all these wizards have
some specific behavior on assign masters step, and in each wizard there is some
logic redefined. All controllers are extending {{wizardStep5Controllert}} and
when you are editing some logic for Installer for example, you may break logic
in some other place. So lets make special mixin with all general logic and make
this logic more customizable to clearly use it in other controllers.
Also assign masters steps do not use real cardinality of master components,
user may add as much host components as much hosts are registered in the
cluster.
This changes are required to provide Select Host step for Ranger Admin HA
Wizard.
