Tao Yang updated YARN-7461: --------------------------- Attachment: YARN-7461.004.patch > 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 > Assignee: Tao Yang > Priority: Minor > Attachments: YARN-7461.001.patch, YARN-7461.002.patch, > YARN-7461.003.patch, YARN-7461.004.patch > > > 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 (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
