Well im trying to send my own event, a ResourcePressureEvent. I have a thread in the ResourceManager that I have created that periodically checks for "resource pressure" - which is whenever the (pending resources + used resources / total resources >= threshold) - and whenever there is "resource pressure" I want to send an event to applications running on the cluster (specifically Spark applications).
