Google doesn't use Hadoop per se; Google uses things like GFS and MapReduce, which they built in-house and have not released. The Hadoop project is an open source reimplementation of various such Google ideas, based on papers Google has published.
To a large extent, there's really nothing interesting in these things; they are roughly 1960s era system services, including the data management parts, but reimplemented such that they allow for high scalability, and/or availability, through very large scale redundancy.
Not much to discuss from a theory standpoint; not very ambitious in anything except scale.
You might look for the mailing lists for the various projects, if you want to talk about any of them specifically.
