Arun C Murthy commented on HADOOP-5884:
---------------------------------------

Can we also add the number of slots to the UI?

> 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.
