> Currently the queuing framework (introduced in YARN-2877) in the NM that handles opportunistic
containers, are pre-empts opportunistic containers only when resources are need to start guaranteed
containers.
> It currently does not handle situations where a guaranteed container resources have been
increased. Conversely, if a guaranteed (or opportunistic) container's resources have been
decreased, the NM must start queued opportunistic containers waiting on the newly available
resources.
