> For example:
> 'mapreduce.map.memory.mb' depends on 'yarn.scheduler.maximum-allocation-mb' 
> and 'yarn.scheduler.minimum-allocation-mb'. 
> *The case:*
> 'yarn.scheduler.minimum-allocation-mb' was changed, but 
> 'yarn.scheduler.maximum-allocation-mb' not. In this case recommendations will 
> use provided value for the first property and recommended value for the 
> second. 'mapreduce.map.memory.mb' will be recalculated incorrectly.
> *Expected:*
> Use the provided values for both properties.
