> When YARN-9892 gets committed, this part will become unnecessary:
> {noformat}
>     // Validate ordering policy
>     if (queueConverter.isDrfPolicyUsedOnQueueLevel()) {
>       if (queueConverter.isFifoOrFairSharePolicyUsed()) {
>         throw new ConversionException(
>             "DRF ordering policy cannot be used together with fifo/fair");
>       } else {
>         capacitySchedulerConfig.set(
>             CapacitySchedulerConfiguration.RESOURCE_CALCULATOR_CLASS,
>             DominantResourceCalculator.class.getCanonicalName());
>       }
>     }
> {noformat}
> We will be able to freely mix fifo/fair/drf, so let's get rid of this strict check and also rewrite {{FSQueueConverter.emitOrderingPolicy()}}.
