Thanks for replying namit..
It is motivating to receive a mail from the authors of Hive :).
I filed the jira based on the discussion..
https://issues.apache.org/jira/browse/HIVE-1938
I will try to update my idea asap.
Thanks

Bharath,
This would be great.
Why don¹t you write up something about how you are planning to proceed ?
File a new jira and load some design notes/spec. there.
We can definitely sync up. from there.
This feature would be very useful to the community - We, at facebook,
Would definitely like to us
Hi Ning,Anja,
I am doing my Masters thesis on this topic . I have implemented all
SQL features like joins , selects etc on top of Hadoop (before knowing
about Hive) and we have derived some basic cost-models for join
re-ordering which seem to be working fine on some basic scales of TPCH
datasets .
Hi Anja,
As you noticed Hive only have limited supports for cost-baesd optimization. One
of the reasons is that Hive used to have very small number of optional
execution plans to choose from. One exception is mapjoin vs common joins.
Liying Tang had some work on his last intern to convert commo
I think there is a developer mailing list ... that is probably the best
place for this question.
Also, I think there is a cost-based query optimizer in the works somewhere.

Hi!
I'm a graduate student from Georgia Tech and I'm working with Hive for a
research project. I am interested in query optimization and the Hive
MetaStore in that context. Working through the documentation and code, I
noticed that the implementation right now is using a rule-based
