             Summary: 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


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.
