> 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.
