Subject [jira] [Created] (YARN-3547) Apps that have no resource demand should not participate scheduling
Date Mon, 27 Apr 2015 07:46:39 GMT
Xianyin Xin created YARN-3547:
---------------------------------

             Summary: Apps that have no resource demand should not participate scheduling
                 Key: YARN-3547
                 URL: https://issues.apache.org/jira/browse/YARN-3547
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: scheduler
            Reporter: Xianyin Xin


At present, all of the 'running' apps participate the scheduling process, however, most of
them may have no resource demand on a production cluster, as the app's status is running other
than waiting for resource at the most of the app's lifetime. It's not a wise way we sort all
the 'running' apps and try to fulfill them, especially on a large-scale cluster which has
heavy scheduling load.
