Dmitriy V. Ryaboy commented on PIG-1354:
----------------------------------------
Ashutosh, nice brainstorm, but I think that if you are to the point of
actually writing java, you should write java. In a proper IDE. With
highlighting, intellisense, javadoc lookup, and all those other awesome bells
and whistles. Plus, reusable code and all that.
To Alan's earlier point -- I think it would be valuable to allow bags
(transformed into arrays) as arguments. That opens up a large set of
statistical functions from Apache Commons, for example. Wouldn't work for
giant bags that don't fit into memory, but nice for smaller groups.

> The need to create wrapper UDFs for simple Java functions creates unnecessary
> work for Pig users, slows down the development process, and produces a lot of
> trivial classes. We can use Java's reflection to allow invoking a number of
> methods on the fly, dynamically, by creating a generic UDF to accomplish this.
