> Issue Type: Task
> Reporter: Ray Chiang
> Assignee: Wilfred Spiegelenburg
> Priority: Major
>
> This section of code exists in the various schedulers in the method nodeUpdate():
> {code}
> // If the node is decommissioning, send an update to have the total
> // resource equal to the used resource, so no available resource to
> // schedule.
> // TODO: Fix possible race-condition when request comes in before
> // update is propagated
> if (nm.getState() == NodeState.DECOMMISSIONING) {
> this.rmContext
> .getDispatcher()
> .getEventHandler()
> .handle(
> new RMNodeResourceUpdateEvent(nm.getNodeID(), ResourceOption
> .newInstance(getSchedulerNode(nm.getNodeID())
> .getAllocatedResource(), 0)));
> }
> {code}
> Investigate the TODO section.
