    Description

      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.
