Subject [jira] Commented: (PIG-928) UDFs in scripting languages
Date Wed, 09 Jun 2010 20:46:22 GMT

    [ https://issues.apache.org/jira/browse/PIG-928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12877197#action_12877197

Arnab Nandi commented on PIG-928:
---------------------------------

> register 'test.py' lang python;

How does one define an arbitrary "lang"? e.g. I would like to introduce Scala as a UDF engine,
preferably as a jar itself. i.e. something like:

register scalascript.jar;
register 'test.py' USING scala.Engine();

> 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.
