---------------------------------

             Summary: YARN limit number of simultaneously running containers in the application level
                 Key: YARN-8009
                 URL: https://issues.apache.org/jira/browse/YARN-8009
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: yarn
    Affects Versions: 3.0.0
            Reporter: Sachin Jose


It would be really useful if the user can specify maximum containers can be running simultaneously in the application level. Most of the long running YARN application can be benefited out of it. At this moment, the only available option to restrict resource over usage of long running is in the YARN resource manager queue level.
