HostComponentStateEntity jtHostComponentStateEntity = serviceComponentDesiredStateEntityJT.getHostComponentStateEntities().iterator().next();
- Might throw Null pointer if service is created but now host assigned ?

Rest looks good.

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.
