In other words, we know how many containers were preempted but we > don't have a good measure of how much work was lost as a result of preemption. > We should add this metric so we can analyze how much work preemption is > costing on a grid and better track which jobs were heavily impacted by it. A > job that has 100 containers preempted that only lasted a minute each and were > very small is going to be less impacted than a job that only lost a single > container but that container was huge and had been running for 3 days. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
