 ]

Peter Bacsko updated YARN-10505:
--------------------------------
    Description: 
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.
