Dmitriy V. Ryaboy commented on PIG-2880:
----------------------------------------
Isn't this just a special case of substring?
If you do feel strongly that this is a useful udf, I would like to suggest a
couple of improvements:
* use PrimitiveEvalFunc<String, String> instead of EvalFunc. It'll take care of
null or empty inputs, etc, which the UDF you proposed will blow up on.
* why add an empty string to a char? String.valueOf is quite a bit more
efficient.
> Pig current releases lack a UDF charAt.This UDF returns the char value at the
> specified index.
