Alan Gates commented on PIG-904:
I don't understand what the issue is here. CONCAT does not take doubles. The
script above tries to pass it a double, and Pig properly says you can't do
that. Is the issue that an implicit cast isn't inserted here? I don't think
Pig currently does implicit casts to match possible UDF signatures.

Key: PIG-904
URL: https://issues.apache.org/jira/browse/PIG-904
Project: Pig
Issue Type: Bug
Affects Versions: 0.4.0
Reporter: Pradeep Kamath
Assignee: Alan Gates
Fix For: 0.9.0
Script showing the problem:
{noformat}
a = load '/user/pig/tests/data/singlefile/studenttab10k' as (name, age,
gpa:double); b = foreach a generate CONCAT(gpa, 'dummy'); dump b;
Error shown:
2009-08-03 17:04:27,573 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
1045: Could not infer the matching function for org.apache.pig.builtin.CONCAT

Jeff Zhang commented on PIG-904:
BTW, I noticed that the logic in TypeCheckingVisitor is a bit complex.
I think we need a clear documentation about the type checking and some code
re-factoring work.
