Hello,
At this point, I have implemented a standalone version of the
1-bucket-theta join algorithm described in the northeastern paper on
Hadoop MR, and would like to start porting it to Hive.
I have been looking at the code and believe that the main goal would be to
implement a new
Hi Andres,
Glad to hear about the progress!
Vikram is a hive join implementation expert. He can guide you through this.
We can setup a webex or google hangout and discuss this. Does sometime
next week work for you ? (Please let us know some hours that work for
you, in Pacific time zone).
Ok, that would be great! Except for Monday and Friday, I could meet any
day next week in the afternoon (Pacific time), since it is the end of the
day for me.
Thanks a lot,
Andrés

So, I'd like to get started on this. The description in the design doc and the
theta join paper from Northeastern seem like a good place to start, to have a
baseline that I can later use for the more specific join algorithms I want to
try.
I created a JIRA account, and my username is
You can start your work from JoinOperator. Before that, you should follow the

Yes, the theta join paper in northeastern is a good place to start.
There is also a presentation from the folks in youtube, which is also
very useful.
I had a look at this issue as well earlier, and I had written up a
rough proposal. I had not organized the document well enough for
sharing
I don't have cycles for working on it in the next month or two. Maybe
after that.

This is a great pointer, Szehon and Brock, thank you. I will catch up with the
material on theta joins and circle back.

From Hive side, there has been some thought on the subject here:
https://cwiki.apache.org/confluence/display/Hive/Theta+Join, it has some
ideas but nobody has gotten around to giving it a try. It might be of
interest.
Thanks

Nice, it'd be great if someone finally implemented this :)

I am interested in learning more about the current support for non-equijoins in
Hive and/or other Hadoop SQL engines, and in getting feedback about community
interest in more extensive support for such a feature. I intend to work on this
