Santhosh Srinivasan updated PIG-320: ------------------------------------ Patch Info: [Patch Available] > The parser/type checker should use the getSchema method of UDFs to deduce > return type/schema > -------------------------------------------------------------------------------------------- > > Key: PIG-320 > URL: https://issues.apache.org/jira/browse/PIG-320 > Project: Pig > Issue Type: Bug > Components: impl > Affects Versions: types_branch > Reporter: Santhosh Srinivasan > Assignee: Santhosh Srinivasan > Fix For: types_branch > > Attachments: udf_outputSchema.patch > > > Currently, the parser/type checker uses the getReturnType to deduce the > return type of the user defined function (UDF). This mechanism is > satisfactory only for basic types (int, long, ...); for composite types > (tuple, bag), the schema is also required.The abstract class EvalFunc > interface exposes the outputSchema to deduce the return type/schema of the > UDF. The parser/type checker should use this method to figure out the return > type/schema of the UDF and use it appropriately. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
