Tao Yang created YARN-7461: ------------------------------ Summary: DominantResourceCalculator#ratio calculation problem when right resource contains zero value Key: YARN-7461 URL: https://issues.apache.org/jira/browse/YARN-7461 Project: Hadoop YARN Issue Type: Bug Affects Versions: 3.0.0-alpha4 Reporter: Tao Yang Priority: Minor
Currently DominantResourceCalculator#ratio may return wrong result when right resource contains zero value. For example, there are three resource types such as <memory-mb, vcores, vssd>, leftResource=<5, 5, 0> and rightResource=<10, 10, 0>, we expect the result of DominantResourceCalculator#ratio(leftResource, rightResource) is 0.5 but currently is NaN. There should be a verification before divide calculation to ensure that dividend is not zero. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
