> 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: Minor

> Attachments: YARN-4256.001.patch, YARN-4256.002.patch

>
> 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.
