> For applicaitons in zero-capacity queues, queueUsagePercentage is wrongly calculated to INFINITY with expression (queueUsagePercentage = usedResource / (totalPartitionRes * queueAbsMaxCapPerPartition) when the queueAbsMaxCapPerPartition=0.
> We can add a precondition （queueAbsMaxCapPerPartition != 0） before this calculation to fix this problem.
