>
> In the fair scheduler, containers are chosen for preemption in the following
> way:
> All containers for all apps that are in queues that are over their fair share
> are put in a list.
> The list is sorted in order of the priority that the container was requested
> in.
> This means that an application can shield itself from preemption by
> requesting it's containers at higher priorities, which doesn't really make
> sense.
> Also, an application that is not over its fair share, but that is in a queue
> that is over it's fair share is just as likely to have containers preempted
> as an application that is over its fair share.
