> The FairScheduler's configuration has the following defaults (from the code: 
> javadoc):
> {noformat}
> In new style resources, any resource that is not specified will be set to 
> missing or 0%, as appropriate. Also, in the new style resources, units are 
> not allowed. Units are assumed from the resource manager's settings for the 
> resources when the value isn't a percentage. The missing parameter is only 
> used in the case of new style resources without percentages. With new style 
> resources with percentages, any missing resources will be assumed to be 100% 
> because percentages are only used with maximum resource limits.
> {noformat}
> This is not documented in the hadoop yarn site FairScheduler.html. It is 
> quite intuitive, but still need to be documented though.
