Fair Scheduler configuration defaults are not documented in case of min and maxResources

      The FairScheduler's configuration has the following defaults (from the code: javadoc):

      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.

      This is not documented in the hadoop yarn site FairScheduler.html. It is quite intuitive, but still need to be documented though.
