> URL: https://issues.apache.org/jira/browse/MYRIAD-135
> Project: Myriad
> Issue Type: Bug
> Components: Scheduler
> Affects Versions: Myriad 0.1.0
> Reporter: Sarjeet Singh
> Assignee: DarinJ
>
> I hit a NullPointerException when myriad-scheduler was receiving offers from
> mesos & offer was missing some resource entity info e.g. (cpu/memory/ports).
> The exception is caused from the following code:
> https://github.com/mesos/myriad/blob/phase1/myriad-scheduler/src/main/java/com/ebay/myriad/scheduler/event/handlers/ResourceOffersEventHandler.java#L150-L156
> Observed the issue when submit a yarn job and job was ran on CGS NMs, not FGS
> NMs. On further debugging the issue, found the following exception from RM
> log:
> 15/09/11 13:14:22 WARN handlers.StatusUpdateEventHandler: Task: value:
