> MR Job stuck in ACCEPTED status without any progress in Fair Scheduler because there is no resource request for the AM. 
> 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}
