I was going to wait on announcing this until I had more time to optimize and clean this up, but I created an AccumuloDataModel for mahout (specifically for recommendations). I will be honest, this has not been thoroughly tested and recommendations using this are pretty slow. I have some ideas for speeding it up, but haven't had time to implement them.
I’m looking to use Accumulo as a data source for Mahout. It doesn’t appear to be built in, nor does Accumulo appear to include the code, but I’m hoping someone can point me at a blog post or something else that could help. I appreciate whatever help I can get.
