Re: product recommendations engine
Hello Douglass,

you could take a look at Mahout and Myrrix projects. These are two projects thatprovide implementations of recommendation & machine learning algorithms. There are MapReduce implementations as well, to support massive datasets.
In addition, these systems provide client APIs/various integration points, so its easy to integrate them to your system.

Regards,
Sofia

>I don't have any prior experience with Hadoop.  I am also not a statistics expert.  I am a software engineer, however, after looking at the docs, Hadoop still seems pretty intimidating to set up.
