Jason Lowe commented on YARN-8292: ---------------------------------- Thanks for updating the patch! I agree with Eric's comment but otherwise looks good to me. Looks like the QA build bot got bit by someone publishing new snapshots at the same time it was building and it didn't converge. Kicking the QA build again on the latest version to make sure there isn't something lurking underneath the transient build error that needs to be addressed. > Fix the dominant resource preemption cannot happen when some of the resource > vector becomes negative > ---------------------------------------------------------------------------------------------------- > > Key: YARN-8292 > URL: https://issues.apache.org/jira/browse/YARN-8292 > Project: Hadoop YARN > Issue Type: Bug > Components: yarn > Reporter: Sumana Sathish > Assignee: Wangda Tan > Priority: Critical > Attachments: YARN-8292.001.patch, YARN-8292.002.patch, > YARN-8292.003.patch, YARN-8292.004.patch, YARN-8292.005.patch, > YARN-8292.006.patch, YARN-8292.007.patch, YARN-8292.008.patch > > > This is an example of the problem: > > {code} > // guaranteed, max, used, pending > "root(=[30:18:6 30:18:6 12:12:6 1:1:1]);" + //root > "-a(=[10:6:2 10:6:2 6:6:3 0:0:0]);" + // a > "-b(=[10:6:2 10:6:2 6:6:3 0:0:0]);" + // b > "-c(=[10:6:2 10:6:2 0:0:0 1:1:1])"; // c > {code} > There're 3 resource types.
