> ResourceManager SchedulingMonitor could potentially terminate the preemption
> checker thread
> -------------------------------------------------------------------------------------------
>
> Key: YARN-5543
> URL: https://issues.apache.org/jira/browse/YARN-5543
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler, resourcemanager
> Affects Versions: 2.7.0, 2.6.1
> Reporter: Min Shen
> Assignee: Min Shen
> Attachments: YARN-5543.001.patch, YARN-5543.002.patch
>
>
> In SchedulingMonitor.java, when the service starts, it starts a checker
> thread to perform Capacity Scheduler's preemption. However, the
> implementation of this checker thread has the following issue:
> {code}
> while (!stopped && !Thread.currentThread().isInterrupted()) {
> ....
> try {
> Thread.sleep(monitorInterval)
> } catch (InterruptedException e) {
> ....
> break;
> }
> }
> {code}
> The above code snippet will terminate the checker thread whenever it is
> interrupted.
> We noticed in our cluster that this could lead to CapacityScheduler's
> preemption disabled unexpectedly due to the checker thread getting terminated.
> We propose to use ScheduledExecutorService to improve the robustness of this
> part of the code to ensure the liveness of CapacityScheduler's preemption
> functionality.
