> 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.
