> 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.
