Julien Le Dem commented on PIG-928:
-----------------------------------
I like the suggestion. However I would prefer not to use namespaces by default.
Most likely users will register a few functions and use namespaces only when
conflicts happen.
The shortest syntax should be used for the most common use case.
most of the time:
REGISTER /home/alan/myfuncs.py USING python;
B = FOREACH A GENERATE a(x);
when it is needed:
REGISTER /home/alan/myfuncs.py USING python AS myfuncs;
B = FOREACH A GENERATE myfuncs.a(x);
Also register jar does not prefix classes by the jar name so that would be
inconsistent.
REGISTER /home/alan/myfuncs.jar;

> It should be possible to write UDFs in scripting languages such as python,
> ruby, etc. This frees users from needing to compile Java, generate a jar,
> etc. It also opens Pig to programmers who prefer scripting languages over
> Java.
