Prabhu Joseph created YARN-4256: ----------------------------------- Summary: YARN fair scheduler vcores with decimal values Key: YARN-4256 URL: https://issues.apache.org/jira/browse/YARN-4256 Project: Hadoop YARN Issue Type: Bug Components: fairscheduler Affects Versions: 2.7.1 Reporter: Prabhu Joseph Priority: Critical Fix For: 2.7.2
When the queue with vcores is in decimal value, the value after the decimal point is taken as vcores by FairScheduler. For the below queue, <minResources>20000 mb,20 vcores,20.25 disks</minResources> <maxResources>30000 mb,40.2 vcores,30.25 disks</maxResources> When many applications submitted parallely into queue, all were in PENDING state as the vcores is taken as 2 skipping the value 40. The code FairSchedulerConfiguration.java to Pattern match the vcores has to be improved in such a way either throw AllocationConfigurationException("Missing resource") or consider the value before decimal. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
