> 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.
