Daniel Templeton commented on YARN-5774:
----------------------------------------
Thanks for the update, [~yufeigu]! I only see one tiny nit: in the
{{AbstractResourceRequest}} javadocs, {code}{@code ResourceManager}{code}
should be {code}{@link ResourceManager}{code}
> MR Job stuck in ACCEPTED status without any progress in Fair Scheduler if set
> yarn.scheduler.minimum-allocation-mb to 0.

> 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}
