Milind Bhandarkar commented on HIVE-1107:
-----------------------------------------
@jco, @squarecog et al.
I have had initial discussions with Keren about this project. I agree that full
production-quality unification is a lot of work, and would require super-human
effort to get it done in 4 months. So, Keren's internship with Greenplum will
focus on producing a prototype. The approach I have proposed to her involves
taking an open-source execution engine, which has superset of these operators,
which is already proven to work with Hadoop (in fact has Hive implemented on
top of it already), and make sure a subset of pig operators are ported to it.

> Pig and Hive each have their own libraries for handling plan execution. As we
> prepare to invest more time improving Hive's plan execution mechanism we
> should also start to consider ways of building a generic plan execution
> mechanism that is capable of supporting the needs of Hive and Pig, as well as
> other Hadoop data flow programming environments.
