> 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.
