Actually there was another thread about using MR for ML but I didn't see many responses. I use Octave or R for this but it would be useful to know how this is solved using Hadoop. The closest community that has an interest in this could be H2o but they have implemented MR for their engine to solve these problems. That is what I understand. So we may be able to look at their code but that could be tedious.
