             Summary: Upgrade pre-req check code needs to be decoupled from CheckDescription
class
                 Key: AMBARI-18050
                 URL: https://issues.apache.org/jira/browse/AMBARI-18050
             Project: Ambari
          Issue Type: New Feature
          Components: ambari-server
    Affects Versions: trunk
            Reporter: Tim Thorpe
            Assignee: Tim Thorpe


Each pre-req check must add an entry in the CheckDescription enum.  This obviously requires
a change to ambari-server java code.  This limits the ability for third party stacks and extensions
to provide their own pre-req checks.

CheckDescription should be rewritten as a class and each pre-req check class should create
an instance of it.  This will allow stacks and extensions to include their own pre-req checks
in separate jar files without requiring changes to ambari-server java code.
