> 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.
