[jira] Commented: (PIG-1479) Embed Pig in scripting languages
[

Julien Le Dem commented on PIG-1479:
Using the file extension requires a registration mechanism (or hard coded list)
so if it is supported it would be nice to be able to provide the class name of
the scripting implementation as well.
I would like to use my own implementation of the scripting engine (let's say
javascript) by specifying the class name in the command line.
similar to the mecanism for UDFs inclusion:

Register 'test.py' using org.apache.pig.scripting.jython.JythonScriptEngine as

Julien Le Dem commented on PIG-1479:
The end of loop condition in the script can just test for to_join_n emptiness.
It was testing both because it did not know which one was to_join_n.

if (not P.result("to_join_n").iterator().hasNext()):

Julien Le Dem commented on PIG-1479:
The -g parameter on the command line should take two parameters, the scripting
implementation instance name and the script itself.
That way we can have several scripting implementations.

java -cp pig.jar: org.apache.pig.Main -x local -g jython

ScriptEngine scriptEngine = ScriptEngine.getInstance(instanceName);
scriptEngine.run(new PigServer(pigContext), file);
