Thejas M Nair updated PIG-1616: ------------------------------- Status: Patch Available (was: Open) > 'union onschema' does not use create output with correct schema when udfs are > involved > -------------------------------------------------------------------------------------- > > Key: PIG-1616 > URL: https://issues.apache.org/jira/browse/PIG-1616 > Project: Pig > Issue Type: Bug > Affects Versions: 0.8.0 > Reporter: Thejas M Nair > Assignee: Thejas M Nair > Fix For: 0.8.0 > > Attachments: PIG-1616.1.patch > > > 'union onshcema' creates a merged schema based on the input schemas. It does > that in the queryparser, and at that stage the udf return type used is the > default return type. The actual return type for the udf is determined later > in the TypeCheckingVisitor using EvalFunc.getArgsToFuncMapping(). > 'union onschema' should use the final type for its input relation to create > the merged schema. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
