  - Use volatile and AtomicIntegers to be thread safe
    
    Modify the fields in ReplicationState class to be volatile and
    AtomicIntegers so that changes to them are reflected to other
    threads. By not doing so, modifications made by one thread to
    these fields may not be reflected instantly depending on
    cpu caching thus resulting in incorrect state
