Richard Ding updated PIG-1479:
------------------------------
Attachment: PIG-1479_4.patch
Attaching patch that addresses above comments:
* One can use --embedded option to specify his/her favorite script engine
classname or keyword. For example
{code}
java -cp pig.jar:jython.jar org.apache.pig.Main --embedded jython myscript.py
{code}
* Implemented the proposed approach of separating frontend control flow
script from backend UDF in scripting language. One needs to explicitly register
UDF in Pig Latin or embedded Pig.
* Both compile() and bind() methods return objects. So one can write code in
jython script like this:
{code}
results = pig.compile("<Pig Latin>").bind({param:value, ...}).run()
{code}
* One can also run embedded scripts using PigRunner.

> 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.
