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

             Summary: Ambari version history: Add ambari_version_history table 
for record keeping history of ambari versions
                 Key: AMBARI-16030
                 URL: https://issues.apache.org/jira/browse/AMBARI-16030
             Project: Ambari
          Issue Type: Task
          Components: ambari-server
    Affects Versions: 2.4.0
            Reporter: Nahappan Somasundaram
            Assignee: Nahappan Somasundaram
             Fix For: 2.4.0


When investigating customer issues, information about history about Ambari 
versions is missing. We rely on this information to be provided in the EAR. 
Many times information in the EAR is inaccurate. Also information about when 
the Ambari upgrades actually happened in the past is completely missing. 

Instead of relying on this information to be provided, Ambari should record 
Ambari upgrade history in Ambari DB.
