Miklos Szegedi commented on YARN-6677:
--------------------------------------
Indeed. How about a comparator with a condition?
# It would compare and list opportunistic containers first to kill then
guaranteed ones
# If the container is in the opportunistic group it would list ones with later
launch time regardless of bursting to preserve pre-oversubscription behavior.
# If the container is in the guaranteed group it would list the ones bursting
first and then the ones with later launch time.
> Preempt opportunistic containers when root container cgroup goes over memory
