Julien Le Dem commented on PIG-1471:
------------------------------------
If the function definition is inline in a DEFINE statement then the
@outputSchema decorator is not that usefull anymore.
Also the current syntax already enables doing something similar:
{code}
DEFINE hellopig org.apache.pig.scripting.jython.JythonFunction('def
helloworld():\n\treturn (\'Hello, World\')', 'x:{t:(word:chararray)}');
{code}
so I'm not sure extending the syntax is necessary unless it let the user type
UDFs without escaping (\n \` ...)
Something like:
{code}
DEFINE hellopig USING
org.apache.pig.scripting.jython.JythonScriptEngine('x:{t:(word:chararray)}') AS
def helloworld():
return ('Hello, World')';
ENDDEFINE
{code}

> 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. It should be possible to write these scripts inline as part of pig
> scripts. This feature is an extension of
