> Fair scheduler should support preemption within queue

>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: fairscheduler
>    Affects Versions: 2.6.0
>            Reporter: Tao Jie

> Now each app in fair scheduler is allocated its fairshare, however  fairshare resource
is not ensured even if fairSharePreemption is enabled.
> Consider: 
> 1, When the cluster is idle, we submit app1 to queueA,which takes maxResource of queueA.
 
> 2, Then the cluster becomes busy, but app1 does not release any resource, queueA resource
usage is over its fairshare
> 3, Then we submit app2(maybe with higher priority) to queueA. Now app2 has its own fairshare,
but could not obtain any resource, since queueA is still over its fairshare and resource will
not assign to queueA anymore. Also, preemption is not triggered in this case.
> So we should allow preemption within queue, when app is starved for fairshare.
