    Overrides:
    
    getSizeToCheck in class IncreasingToUpperBoundRegionSplitPolicy
    
    Returns:
    flushSize * 2 if there's exactly one region of the table in question found on this regionserver. Otherwise max file size. This allows a table to spread quickly across servers, while avoiding creating too many regions.
