Ankur updated PIG-958:

    Attachment: 958.v3.patch

                 Thanks for your review comments. I have incorporated the 
suggestions provided in the code review. The code is vastly simplified, cleaner 
and more readable :-). 

Unit test now pass in local mode but fail in cluster mode after taking an 
update of Pig code base. The error I see is :-
 expected: file:///

Looks like a config issue with org.apache.pig.test.MiniCluster in the latest 
pig code. I didn't get time to debug this as I am going on a vacation. 
Regardless, I have attached the new patch for your review. Please suggest what 
needs to be done to pass the unit test in cluster mode.

> Pig users often face the need to split the output records into a bunch of 
> files and directories depending on the type of record. Pig's SPLIT operator 
> is useful when record types are few and known in advance. In cases where type 
> is not directly known but is derived dynamically from values of a key field 
> in the output tuple, a custom store function is a better solution.
