> Fix enumerable code generator to handle UDFs that throws checked Exceptions
> ---------------------------------------------------------------------------
>
> Key: CALCITE-3195
> URL: https://issues.apache.org/jira/browse/CALCITE-3195
> Project: Calcite
> Issue Type: Bug
> Components: core, piglet
> Reporter: Khai Tran
> Priority: Major
>
> Current auto-generated code cannot handle UDFs that throws checked exception,
> so the auto-generated code fails to compile.
> In piglet, the PigUDFWrapper class is a workaround for handling IOException
> from some Pig UDFs.
> Need to fix the codegen engine, then remove PigUDFWrapper class.
