> Currently, when a high memory job is scheduled by the capacity scheduler, each task scheduled counts only once in the capacity of the queue, though it may actually be preventing other jobs from using spare slots on that node because of its higher memory requirements. In order to be fair, the capacity scheduler should proportionally (with respect to default memory) account high memory jobs as using a larger capacity of the queue.
