> Method Fairscheduler#shouldAttemptPreemption doesn't consider resources other
> than vcore and memory. We may need to rethink it in the resource type
> scenario. cc [[email protected]], [~wilfreds] and [~snemeth].

> if (context.isPreemptionEnabled()) {
> return (context.getPreemptionUtilizationThreshold() < Math.max(
> (float) rootMetrics.getAllocatedMB() /

> (float) rootMetrics.getAllocatedVirtualCores() /
> getClusterResource().getVirtualCores()));
