> Currently CS preemption monitor doesn't consider execution type of containers, so OPPORTUNISTIC containers maybe selected and killed without effect.
> In some scenario with OPPORTUNISTIC containers, not even preemption can't work properly to balance resources, but also some apps with OPPORTUNISTIC containers maybe effected and unable to work.
