             Summary: Expose Upgrade Check Classes via an Ambari Client Library
                 Key: AMBARI-24737
                 URL: https://issues.apache.org/jira/browse/AMBARI-24737
             Project: Ambari
          Issue Type: Task
    Affects Versions: 2.8.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
             Fix For: 2.8.0


The pre-upgrade check framework inside of Ambari needs to be migrated to the Ambari API/SPI being developed as part of AMBARI-24685 so that 3rd party stack developers can use this to compile and deliver their own custom upgrade checks for their stack.

The following items should be included:
- A way to obtain configuration information about the cluster's services
- Topology information, including services installed and the components/hosts of the cluster

The existing checks which are not stack-specific should remain in Apache and altered to use the new framework. This means that the {{ambari-server}} project will have a dependency on the new module created as part of AMBARI-24685.
