Subject Re: Embedding mahout in a java app
Date Wed, 02 Nov 2011 11:34:46 GMT
Thanks Sean.

Looks like I'll have to dig into the code will start from MahoutDriver.

Is there a mode that will work for all algorithms. For example, all
algorithms can run on a single node mode or all algorithms run on a hadoop
mode ( I know Hadoop has a local mode, but that's not what I'm referring
to) or something similar?

I'd like to support the tool to run even without Hadoop as that will be
great for small data sets for someone to try out and play around with.
Maybe there's another java library that already does this.
