Benjamin Teke commented on YARN-10505:
--------------------------------------
After an offline discussion with [~gandras] I reopened this ticket. This track
the percentage mode changes, after completing this item a relative to the
parent and a relative to the whole cluster (aka Absolute percentage) mode
should be available.
> Extend the maximum-capacity property to react to weight mode changes

> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Benjamin Teke
> Priority: Major

> The property root.users.maximum-capacity could mean the following things:
> * Relative 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.
> * Absolute Percentage: maximum capacity expressed as a percentage of the
> overall cluster capacity.
>
> Note that Fair Scheduler supports the following settings:
> * Single percentage (absolute)
> * Two percentages (absolute)
> * Absolute resources
>
> It is recommended that all three formats are supported for maximum-capacity
> after introducing weight mode.
