---------------------------------------------

             Summary: UI does not display correct versions in 'Stack and Versions' when multiple "same" HDP versions exist
                 Key: AMBARI-22381
                 URL: https://issues.apache.org/jira/browse/AMBARI-22381
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.6.0
            Reporter: Georgios Andrianakis
            Priority: Minor


Essentially when multiple versions of HDP exist, for example 2.6.0, 2.6.2 and 2.6.3 have been installed at various times, the UI in *Admin* / *Stacks and Versions* displays incorrect version numbers, both for installed and candidate services.
In the example case mentioned above, Ambari Web was displaying the service versions that corresponded to HDP 2.6.0 (which was the oldest of the 2.6 HDP platforms that had been installed).

I believe that the root of the issue is the javascript function _loadServiceVersionFromVersionDefinitionsSuccessCallback_. 
In that function a Stack is chosen only based on the truncated version (2.6 in the example).

I essentially side-stepped the problem by deleting the database records in various tables that corresponded to HDP 2.6.0 and HDP 2.6.2.
