    Not necessarily (set them directly).  We have a use case where certain hosts are restricted
to use a subset of ports for communication purposes.  On yarn you might end up with multiple
executors on a single host but they can't share a port so having a range that they automatically
find a free one on is best.  
    
    I was actually wanting to implement this as its needed for some of our customers.
