> Reproduce this error in chronological order:
> 1. AM started and requested 1 container with schedulerRequestKey#1 :
> ApplicationMasterService#allocate --> CapacityScheduler#allocate --> SchedulerApplicationAttempt#updateResourceRequests --> AppSchedulingInfo#updateResourceRequests
> Added schedulerRequestKey#1 into schedulerKeyToPlacementSets
> 2. Scheduler allocatd 1 container for this request and accepted the proposal
> 3. AM removed this request
> ApplicationMasterService#allocate --> CapacityScheduler#allocate --> SchedulerApplicationAttempt#updateResourceRequests --> AppSchedulingInfo#updateResourceRequests --> AppSchedulingInfo#addToPlacementSets --> AppSchedulingInfo#updatePendingResources
> Removed schedulerRequestKey#1 from schedulerKeyToPlacementSets)
> 4. Scheduler applied this proposal
> CapacityScheduler#tryCommit --> FiCaSchedulerApp#apply --> AppSchedulingInfo#allocate
> Throw NPE when called schedulerKeyToPlacementSets.get(schedulerRequestKey).allocate(schedulerKey, type, node);
