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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
