Mathias Herberts commented on PIG-1804:
---------------------------------------
The Algebraic interface has three methods which return class names to be fed to
FuncSpec.
This approach pretty much forbids dynamically created Algebraic UDFs using pure
(with no compilation phase) scripting languages (not only Jython, but Groovy,
JavaScript are also concerned).
What would the impact be if Algebraic was refactored so
get{Initial,Intermed,Final} return class instances instead of class names?
> Alow Jython function to implement Algebraic and/or Accumulator interfaces
