> YARN-1051 introduces the notion of reserving resources prior to job
> submission. A reservation is active from its arrival time to deadline but in
> the interim there can be instances of time when it does not have any
> resources allocated. We reject jobs that are submitted when the reservation
> allocation is zero. Instead we should accept & queue the jobs till the
> resources become available.
