>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: capacity scheduler, scheduler preemption, yarn
>    Affects Versions: 2.9.0, 2.8.1, 3.0.0-alpha3
>            Reporter: Eric Payne
>            Assignee: Eric Payne

> {{FifoIntraQueuePreemptionPlugin#calculateUsedAMResourcesPerQueue}} has the following
code:
> {code}
>     Collection<FiCaSchedulerApp> runningApps = leafQueue.getApplications();
>     Resource amUsed = Resources.createResource(0, 0);
>     for (FiCaSchedulerApp app : runningApps) {
> {code}
> {{runningApps}} is unmodifiable but not concurrent. This caused the preemption monitor
thread to crash in the RM in one of our clusters.
