      Description

      This would be very useful in one specific use case:
      if a view is used by both Hive and Impala then all the non-builtin functions it uses have to be Hive UDFs. It would be nice to add the possibility to write a native version too and if Impala would automatically prefer that.

      A possible implementation is to choose a prefix like _impala, and when loading UDFs these prefixis would be removed and __impala_funname() would be preferred over funname()
