He Tianyi created YARN-3902: ------------------------------- Summary: Fair scheduler preempts ApplicationMaster Key: YARN-3902 URL: https://issues.apache.org/jira/browse/YARN-3902 Project: Hadoop YARN Issue Type: Bug Components: fairscheduler Affects Versions: 2.3.0 Environment: 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt2-1~bpo70+1 (2014-12-08) x86_64 Reporter: He Tianyi
YARN-2022 have fixed the similar issue related to CapacityScheduler. However, FairScheduler still suffer, preempting AM while other normal containers running out there. I think we should take the same approach, avoid AM being preempted unless there is no container running other than AM. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
