---------------------------------------------------
Summary: Duplicate TOKENIZE schema
Key: PIG-2691
URL: https://issues.apache.org/jira/browse/PIG-2691
Project: Pig
Issue Type: Bug
Reporter: Gianmarco De Francisci Morales
TOKENIZE produces a fixed named schema that results in duplicates if used more
than once in the same generate statement.
We could paramenterize the schema on the name of the field being tokenized.
{code}
grunt> q = LOAD 'file' AS (source:chararray, target:chararray);
grunt> e = FOREACH q GENERATE TOKENIZE(source), TOKENIZE(target);
