> MR Job stuck in ACCEPTED status without any progress in Fair Scheduler 
> because there is no resource request for the AM. This happened when you 
> configure {{yarn.scheduler.minimum-allocation-mb}} to zero.
> The problem is in the code used by both Capacity Scheduler and Fair 
> Scheduler. {{scheduler.increment-allocation-mb}} is a concept in FS, but not 
> CS. So the common code in class RMAppManager passes the 
> {{yarn.scheduler.minimum-allocation-mb}} as incremental one because there is 
> no incremental one for CS when it tried to normalize the resource requests.
> {code}
>      SchedulerUtils.normalizeRequest(amReq, scheduler.getResourceCalculator(),
>           scheduler.getClusterResource(),
>           scheduler.getMinimumResourceCapability(),
>           scheduler.getMaximumResourceCapability(),
>           scheduler.getMinimumResourceCapability());  --> incrementResource 
> should be passed here.
> {code}
