> Key: PIG-1794
> URL: https://issues.apache.org/jira/browse/PIG-1794
> Project: Pig
> Issue Type: New Feature
> Components: impl
> Affects Versions: 0.9.0
> Reporter: Julien Le Dem
> Assignee: Julien Le Dem
> Fix For: 0.9.0
>
> Attachments: jsScripting.patch
>
>
> The attached patch proposes a javascript implementation for Pig embedding and
> UDFs in scripting languages.
> It is similar to the Jython implementation and uses Rhino provided in the JDK.
> some differences:
> - output schema is provided by: <functionName>.outSchema="<schema>" as
> javascript does not have annotations or decorators but functions are first
> class objects
> - tuples are converted to objects using the input schema (the other way
> around using the output schema)
> The attached patch is not final yet. In particular it lacks unit tests.
> See test/org/apache/pig/test/data/tc.js for the "transitive closure" example
> See the following JIRAs for more context:
> https://issues.apache.org/jira/browse/PIG-928
