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 and wanted to deduct the pending resource
CapacityScheduler#tryCommit --> FiCaSchedulerApp#apply -->
AppSchedulingInfo#allocate
Throw NPE when called
schedulerKeyToPlacementSets.get(schedulerRequestKey).allocate(schedulerKey,
type, node);
