             Summary: Refactor version comparisons to use function
                 Key: AMBARI-8429
                 URL: https://issues.apache.org/jira/browse/AMBARI-8429
             Project: Ambari
          Issue Type: Bug
          Components: stacks
    Affects Versions: 1.7.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
             Fix For: 2.0.0


In Ambari 1.7.0, we started introducing checks for the HDP version like
 
stack_is_hdp22_or_further = not (stack_version.startswith('2.0') or stack_version.startswith('2.1'))
This may lead to problems in future HDP versions.
Instead, we should create a function/class for doing version comparisons.
ambari-server.py already has a method called compare_versions() that compares the each segment of a version (separated by dots).
