LongGang Chen updated YARN-8354:
--------------------------------
Affects Version/s: 3.0.x
Component/s: RM
> SingleConstraintAppPlacementAllocator's allocate does not decPendingResource
> ----------------------------------------------------------------------------
>
> Key: YARN-8354
> URL: https://issues.apache.org/jira/browse/YARN-8354
> Project: Hadoop YARN
> Issue Type: Bug
> Components: RM
> Affects Versions: 3.0.x
> Reporter: LongGang Chen
> Priority: Major
>
> SingleConstraintAppPlacementAllocator.allocate() does not
> decPendingResource,only
> reduce ResourceSizing.numAllocations by one.
> may be we should change decreasePendingNumAllocation() from :
>
> {code:java}
> private void decreasePendingNumAllocation() {
> // Deduct pending #allocations by 1
> ResourceSizing sizing = schedulingRequest.getResourceSizing();
> sizing.setNumAllocations(sizing.getNumAllocations() - 1);
> }
> {code}
> to:
> {code:java}
> private void decreasePendingNumAllocation() {
> // Deduct pending #allocations by 1
> ResourceSizing sizing = schedulingRequest.getResourceSizing();
> sizing.setNumAllocations(sizing.getNumAllocations() - 1);
> // Deduct pending resource of app and queue
> if (getExecutionType() == ExecutionType.OPPORTUNISTIC) {
> appSchedulingInfo.decOpportunisticPendingResource(
> schedulingRequest.getNodeLabelExpression(),
> sizing.getResources());
> }else{
> appSchedulingInfo.decPendingResource(
> schedulingRequest.getNodeLabelExpression(),
> sizing.getResources());
> }
> }
> {code}
>
