>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 2.4.0
>            Reporter: Vitaly Brodetskyi
>            Assignee: Vitaly Brodetskyi
>            Priority: Critical
>             Fix For: 2.5.0

> 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.
