Minor Description
When the Fifo scheduler receives a heartbeat from a NM the NM appears as a HOST:PORT. When a request is made to the scheduler to have a container run on a given host that request is given just as HOST. Right now the FIFO scheduler does not use just the HOST part of HOST:PORT for the comparison. This is minor because very few people will run with the FIFO scheduler on a cluster at all, but it still needs ot be fixed.
