Sunil G commented on YARN-5130:
-------------------------------

Yes. I agree with your point. There should be a strict notion while making 
changes on a Stable interface especially to those exposed to client and other 
modules. We could have some test cases to detect this, still a hack in test 
cases could take us back to original problem.

> It turns out that slider won't build as the {{ContainerStatus}} and 
> {{NodeReport}} classes have added more abstract methods, so breaking the mock 
> objects.
> While it is everyone's freedom to change things, these classes are both tagged
> {code}
> @Public
> @Stable
> {code}
> Given they aren't stable, can someone mark them as {{@Evolving}}? That way 
> when downstream code breaks, we can be less disappointed
