> Per discussion in MAPREDUCE-5583, FifoScheduler should assign containers that 
> up to the number of containers specified in ResourceRequest for ANY which is 
> not true today. It only check number of ResourceRequest for ANY >0, then go 
> ahead to allocate containers according to other locality request which could 
> exceed the number in ANY. 
> This behavior is not consistent with other Schedulers, like: CS or FS, and 
> not meet our expectation, so we should fix this.
