kyungwan nam created YARN-10567:
-----------------------------------

             Summary: Support parallelism for YARN Service
                 Key: YARN-10567
                 URL: https://issues.apache.org/jira/browse/YARN-10567
             Project: Hadoop YARN
          Issue Type: New Feature
            Reporter: kyungwan nam


YARN Service support job-like by using "restart_policy" introduced in YARN-8080.
But, we cannot set how many containers can be launched concurrently.
This feature is something like "parallelism" in kubernetes.
