Richard Ding updated PIG-1479:
------------------------------
Attachment: PIG-1479_3.patch
Attaching the initial patch that aims to implement the embedding part of the
above proposal.
Notes about the patch:
* Pig executes the top-level Jython statements in the script, no need to write
a main() function.
* You can invoke a Jython script from the command line the same way as you
invoke a standard Pig script as long as the first line of the script is *#!
/usr/bin/python*.
Example:
{code}
java -cp jython.jar:pig.jar myscript.py
{code}
* The run method on ScriptEngine returns a Map<String, PigStats>, with one
entry for each runtime Pig pipeline. For named pipeline, the map key is the
given pipeline name.
* The proposed API is implemented in two classes: _ScriptPigServer_ and
_PigPipeline_.
* The _compile_ method now is a no-op, will be implemented later.

> It should be possible to embed Pig calls in a scripting language and let
> functions defined in the same script available as UDFs.
> This is a spin off of https://issues.apache.org/jira/browse/PIG-928 which
> lets users define UDFs in scripting languages.
