------------------------------------------

Hi Gianmarco
I am Dishara who took part in previous GSoC 2012 in Apache Velocity project and successfully completed the JSR 223 implementation. I would like to contribute to the PIG project since it seems pretty interesting. As far as I understand this project idea is basically to implement a tolerable Stratified sampling algorithm on top of PIG. Correct me If I am wrong. Can you provide a bit more details of what aspects I need to look in and get in to this. (like what exactly expected eventually, so that may be I can provide potential algorithm as a patch to simulate this probably before the proposal)
