------------------------------------------
Summary: Integrate new Add Service Request with stack advisor
layout recommendation
Key: AMBARI-24964
URL: https://issues.apache.org/jira/browse/AMBARI-24964
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: 2.7.2
Reporter: Balázs Bence Sári
Assignee: Balázs Bence Sári
Fix For: trunk
In the new "Add Service" API, users of the API will be able to list out a set
of services that need to be added to an existing cluster, without specifying
any individual components or specifying where the components will be hosted.
In the event that an "Add Service" request is submitted, with only service
names specified, then the "Add Service" deployment code must implement the
following:
1. Based on the services included in the request, make a call to the
StackAdvisor for component layout recommendations.
The following code shows an example of creating this request:
{code}org.apache.ambari.server.api.services.stackadvisor.StackAdvisorHelper#createRecommendationCommand{code}
2. Take the output of the StackAdvisor, and use that to determine the list of
components to install and start, as well as the hosts that will include these
components.
