> The property root.users.maximum-capacity could mean the following things:
> * Parent Percentage: maximum capacity relative to its parent. If it’s set to
> 50, then it means that the capacity is capped with respect to the parent.
> * Cluster Percentage: maximum capacity expressed as a percentage of the
> overall cluster capacity.
>
> Note that Fair Scheduler supports the following settings:
> * Single percentage (cluster)
> * Two percentages (cluster)
> * Absolute resources
>
> It is recommended that all three formats are supported for maximum-capacity
> after introducing weight mode.
