Re: Implementation of Flatten()

[Alan Gates]

flatten is not implemented as a UDF.  It's implemented as part of the  
foreach code, which is in src/org/apache/pig/backend/hadoop/ 
executionengine/physicalLayer/relationalOperators/POForEach.java

Hi,

does anybody know where to find the source code of the flatten()  
function of Pig?
I can't find it in the package "org.apache.pig.builtin" of pig.jar.

Thx in advance,
