Description

the EnsureCurrentState() checks of services throw an IllegalStateException if the state is wrong. If this was changed to YarnException. wrapper services such as CompositeService could relay this direct, instead of wrapping it in their own.

Time to implement mainly in changing the lifecycle test cases of MAPREDUCE-3939 subtasks.
