Nathan Roberts commented on YARN-1011:
--------------------------------------
Won't the scheduler just try to assign it to that application again? Seems like
they'll fight one another. "Here's a container".."No, I don't like this
container".."No really, you should like this container, take it."....
> [Umbrella] Schedule containers based on utilization of currently allocated
> containers

> Currently RM allocates containers and assumes resources allocated are
> utilized.
> RM can, and should, get to a point where it measures utilization of allocated
> containers and, if appropriate, allocate more (speculative?) containers.
