Olga Natkovich updated PIG-1943:
--------------------------------
Fix Version/s: (was: 0.9.0)
> jython functions can use the @outputSchema decorator, but only if in the out
> script that is imported, we should add a builting module pigdecorators.py so
> that developers can import and use them in lib scripts
> ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: PIG-1943
> URL: https://issues.apache.org/jira/browse/PIG-1943
> Project: Pig
> Issue Type: Improvement
> Components: impl
> Affects Versions: 0.8.0, 0.9.0
> Reporter: Woody Anderson
> Assignee: Woody Anderson
> Priority: Minor
> Labels: pig, python, schema, udf
>
> if you have pig udf functions in a pig script, and want to re-use it (i.g.
> import from another script) the decorators must be defined. They will not be,
> due to scoping rules, so the decorators should be available via a standard
> importable module that ships with the jython framework (as we already define
> the decorators as part of initializing the interpreter).
> this simply involves adding an appropriately named: pigdecorators.py to the
> classpath, so a dev can do:
> {quote}
> from pigdecorators import *
> @outputSchema("w:chararray")
> def word():
> return 'word'
> {quote}
> this can be done currently in the primary script, but when
> https://issues.apache.org/jira/browse/PIG-1824 is completed, that script
> would not properly import when used within another script in the future.
