Subject [jira] [Created] (PIG-2937) generated field in nested foreach does not inherit the variable name as the field name
Date Thu, 27 Sep 2012 21:37:07 GMT
Feng Peng created PIG-2937:
------------------------------

             Summary: generated field in nested foreach does not inherit the variable name
as the field name
                 Key: PIG-2937
                 URL: https://issues.apache.org/jira/browse/PIG-2937
             Project: Pig
          Issue Type: Bug
            Reporter: Feng Peng


{code}
raw_data = load 'xyz' using Loader() as (field_a, field_b, field_c);
records = foreach raw_data {
  generated_field = (field_a is null ? '-' : someUDF(field_b)); 
  GENERATE
    field_c,
    generated_field
  ;
}
describe records;
{code}

One would expect the generated_field to have a field name, similar to the field_c that is
from the original relation. However, Pig currently doesn't assign the field name by default.
It'd be nice if we can assign the variable name as the default field name.
