Learning Apache Mahout

A Mahout command-line example

Now, we will discuss how to cluster objects using the Mahout command line. We start with getting the data first.

Getting the data

We will use the seed dataset from our favorite UCI repository for clustering examples. The dataset is available at https://archive.ics.uci.edu/ml/datasets/seeds.

To download the data, we can execute the following command:

wget https://archive.ics.uci.edu/ml/machine-learning-databases/00236/seeds_dataset.txt

We also have the data downloaded in data/chapter7 in our code base.

Data description

The seed dataset consists of 8 attributes as follows:

Column	Data type
Area (A)	Continuous
Perimeter (P)	Continuous
Compactness (C = 4*pi*A/P^2)	Continuous
Length of kernel	Continuous
Width of ...
