Benjamin Teke updated YARN-10505:
---------------------------------
Description:
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.

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.
* Percentages of different resource types: this would refer to vCores, memory,
GPU, etc... Similarly to the single percentage value, this could either mean
percentage of the parent or percentage of the overall cluster resource.
* Absolute limit: explicit definition of vCores and memory like vcores=20,
memory-mb=16384. This case will be covered in YARN-9936.
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.
> Extend the maximum-capacity property to react to weight mode changes
