> FairSchedulerConfiguration is very strict about the number of space 
> characters between the value and the unit: 0 or 1 space.
> For example, for values like the following:
> {noformat}
> <maxResources>4096  mb, 2 vcores<maxResources>
> {noformat}
> (note 2 spaces)
> This above line fails to parse:
> {noformat}
