----------------------------------

Hi [~snemeth],
Do you have an update for this?
Also I find it quite strange that {{TestFairScheduler.java}} got so many 
imports. Check in your next patch whether all of them are necessary.

> The FairScheduler#getResourceCalculator always returns the default resource 
> calculator. The default calculator is not resource type aware and should only 
> be used if there are no resource types configured.
> We need to make sure that in we the direct hard code reference to 
> {{RESOURCE_CALCULATOR}} is either safe to use in all cases or is not used  in 
> the scheduler.
