> FairScheduler: Disallow preemption from a queue
> Key: YARN-4462
> URL: https://issues.apache.org/jira/browse/YARN-4462
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: fairscheduler
>Affects Versions: 2.6.0
>Reporter: Tao Jie
>Assignee: Tao Jie
> When scheduler preemption is enabled, applications could be preempted if they
> obtain resource over they should take.
> When a mapreduce application is preempted some resource, it just runs slower.
> However, when the preempted application is a long-run service, such as tomcat
> running in slider, the service would fail.
> So we should have a flag for application to indicate the scheduler that those
> application should not be preempted.
