> 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.
