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

             Summary: Upgrade Issue with History Server in HDP 1.
                 Key: AMBARI-5089
                 URL: https://issues.apache.org/jira/browse/AMBARI-5089
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.5.0


Upgrade Issue with History Server in HDP 1.

The following is the issue:

With new HDP 1 work History Server is being treated as a separate component - earlier it was part of JobTracker start/stop/management. When users who are using HDP 1 and just upgrade Ambari they will not have a History Server component. This will mean that in MR there will nto be any History Server running. We need to find a way to make this seem less for the user. 

Best would be add it to our DDL upgrade script where we add a new host componenet History Server on the same host as the JobTracker. 

Feel free to evaluate and propose other solutions.
