> Use threadPool to handle async scheduling threads
> -------------------------------------------------
>
> Key: YARN-10126
> URL: https://issues.apache.org/jira/browse/YARN-10126
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: capacity scheduler
> Affects Versions: 2.9.1
> Reporter: Aihua Xu
> Assignee: Aihua Xu
> Priority: Major
>
> Currently, async scheduling launches individual threads to handle scheduling
> requests. If there is any issues in such threads, the threads exit and no new
> threads get relaunched. Then eventually all the threads die and won't handle
> any new job scheduling.
