I guess I'm pointing out that there are lots of people that have been down this road before. The idea of having Mahout avail via a remote HTTP is pretty cool... but that is more general purpose than a C++ port. Also note the lesson of CLucene. They've done a great job with their C++ port, I used it to gut the internals of HtDig (leaving only the original webspider, configuration, and C/PHP APIs). However, they are constantly chasing the Java Lucene port and only keeps up in fits and starts. - Neal Richter, a mahout lurker On Fri, Feb 5, 2010 at 1:41 PM, Israel Ekpo <israele...@gmail.com> wrote: > Thanks everyone for your responses so far. > > The Apache Hadoop dependency was something I thought about initially but I > still went ahead to ask the question anyways. > > At this time, it would be a better use of resources and time to come up with > a wrapper or HTTP server/client set up of some sort. > > My reasoning behind this is because of the Hadoop dependency and the > volatile nature of the API as pointed out by Sean and Robin > > Thanks again for all your responses. > > On Thu, Feb 4, 2010 at 12:22 PM, Atul Kulkarni <atulskulka...@gmail.com>wrote: > >> Hey guys, >> >> My 1 cent... >> >> I would be really happy to contribute to this task of enabling use of >> Mahout >> via C++ (Wrapper / Port either way).
