> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: fairscheduler
> Affects Versions: 2.9.0
> Reporter: Karthik Kambatla
> Assignee: Yufei Gu

> FSStarvedApps currently uses a BlockingQueue to store starved applications.
> This leads to storing the apps in the order they were processed instead of
> their priorities. Using a PriorityQueue will ensure we preempt for the
> highest priority apps first.
