> 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.
