Julien Le Dem commented on PIG-928:
-----------------------------------
Aniket, this is assuming the ScriptEngine requires only one jar.
I would suggest instead having a method ScriptEngine.init(PigContext) that
would be called after the ScriptEngine instance has been retrieved from the
factory.
That would let the script engine add whatever is needed to the job.
{code}
if(scriptingLang != null) {
ScriptEngine se = ScriptEngine.getInstance(scriptingLang);
//pigContext.scriptJars.add(se.getStandardScriptJarPath());
se.init(pigContext);
se.registerFunctions(path, namespace, pigContext);
}
{code}
Have a good week end, Julien

> 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.
