Subject Re: Hive projects for Google Summer of code 2012 ?
Date Wed, 08 Feb 2012 02:32:58 GMT
Hi Namit Jain, I'm Alexis, I'm a master student, I'm studying in Cinvestav,
df Mexico.
I'm interesting in collaborating with Hive. I'd like to do my thesis work
in something about Hive.
I'd like to participate in Google Summer of Code 2012 too.

The issues that you propose I find interesting, particularly in the next
issues:
* The topic 2. Indexed Joins.
* [PO] Optimize Joins using Bloom Filters of this page
https://cwiki.apache.org/confluence/display/Hive/Roadmap.

Can you tell me something more about it?
What is problem to be solved?
What benefits we hope to gain?

This because I want to raise my thesis problem.
By another hand, can you be my mentor in Google Summer of Code, if I work
with this topics?

Thanks.
