Check for Application priority. If priority is available, then return the > highest priority job. > 2. Otherwise continue with existing logic such as Fair Share comparison and > App ID comparison and then TimeStamp comparison. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
