Eric Payne commented on YARN-4218: ---------------------------------- [~lichangleo], as for the trunk patch, please go ahead and fix the {{hadoop-yarn-api}} javadoc warnings. I don't think you can fix the {{hadoop-yarn-server-resourcemanager}} warnings because it's related to the underscore: bq. RMAppBlock.java:179: warning: '_' used as an identifier > Metric for resource*time that was preempted > ------------------------------------------- > > Key: YARN-4218 > URL: https://issues.apache.org/jira/browse/YARN-4218 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Reporter: Chang Li > Assignee: Chang Li > Attachments: YARN-4218.2.patch, YARN-4218.2.patch, YARN-4218.2.patch, > YARN-4218.2.patch, YARN-4218.3.patch, YARN-4218.4.patch, YARN-4218.5.patch, > YARN-4218.branch-2.2.patch, YARN-4218.branch-2.patch, YARN-4218.patch, > YARN-4218.trunk.2.patch, YARN-4218.trunk.3.patch, YARN-4218.trunk.patch, > YARN-4218.wip.patch, screenshot-1.png, screenshot-2.png, screenshot-3.png > > > After YARN-415 we have the ability to track the resource*time footprint of a > job and preemption metrics shows how many containers were preempted on a job. > However we don't have a metric showing the resource*time footprint cost of > preemption. 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
