-------------------------------
Summary: Use threadPool to handle async scheduling threads
Key: YARN-10126
URL: https://issues.apache.org/jira/browse/YARN-10126
Project: Hadoop YARN
Issue Type: Improvement
Components: capacity scheduler
Affects Versions: 2.9.1
Reporter: Aihua Xu
Assignee: Aihua Xu
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.
