Vinod K V commented on HADOOP-4373:
-----------------------------------
Few comments. We can
- stop looking at more queues once we spot a queue with zero guaranteed
capacity, in TaskSchedulingMgr.assignTasks. This works because of the ordering
of queues.
- also skip queues with on zero capacities in
TaskSchedulingMgr.reclaimCapacity. This can avoid some unnecessary comparisons.
- have a check for queues with zero capacity *percentages*. This is perhaps
what Vivek intended.
