Siddharth Seth commented on YARN-811:
-------------------------------------

Trying to do this would probably mean that AbstractService would be aware of 
CompositeService. Depends on whether there's value in doing this. Looking at 
the code base - there's places where a Composite Service makes a super.start() 
call in the middle of it's start code - and that may complicate this 
(MRAppMaster for example)
                
> Add a set of final _init/_start/_stop methods to CompositeService

> Classes which implement AbstractService no longer need to make a super.init, 
> start, stop call. The same could be done for CompositeService as well.
