    [CARBONDATA-2766] Added null check on filestatus

    **Problem:**  While doing any operation on Carbon File if file status acquiring throws exception then it is logged and not thrown again therefore if any further operation on that object required filestatus then it can throw NPE.
   
    **Solution:** Add null check and throw proper exception.

    why not throw IOException so that user can explicitly know and handle the exception.
    In your implementation, when there is a problem, the user will get RTE instead of NPE which I think there’s no difference.

    Besides, there are too many duplicate code here to check null.
   
    If null will cause EXCEPTION for all the operations, why not throw EXCEPTION as soon as the variable filestatus is assigned in setter or constructor?
