Julien Le Dem updated PIG-2705: ------------------------------- Resolution: Fixed Fix Version/s: 0.11 Status: Resolved (was: Patch Available) committed to trunk. Thanks Josh! > outputSchema modification from scripting UDFs > --------------------------------------------- > > Key: PIG-2705 > URL: https://issues.apache.org/jira/browse/PIG-2705 > Project: Pig > Issue Type: Improvement > Affects Versions: 0.9.2, 0.10.0 > Reporter: Josh Levy > Fix For: 0.11 > > Attachments: PIG-2705-1.patch, PIG-2705.2.patch > > > The examples for @schemaFunction that I've seen on the web > (http://pig.apache.org/docs/r0.10.0/udf.html#decorators) tend to be trivial > ones that return the same schema passed in. I had a problem where I wrote a > python udf that added a new field into a tuple in a bag. I ended up not > specifying schema in python and then casting in pig. How does the community > feel about making it easier to generate a dynamic schema from a scripting UDF? > This could be done by modifying JythonFunction.outputSchema to handle > outputSchemaFunc returning a string like @outputSchema does, or by exposing a > public api that makes it easier to manipulate > org.apache.pig.impl.logicalLayer.schema.Schema -- This message is automatically generated by JIRA.
