Mahout小案例学习，实现k-means算法。

环境：OS：Centos 6.5 x64 & Soft：Hadoop 1.2.1 & Mahout 0.9

1、下载测试数据

[huser@master hadoop]$ wget http://archive.ics.uci.edu/ml/databases/synthetic_control/synthetic_control.data

2、数据拷贝到HDFS

[huser@master hadoop]$ hadoop-1.2.1/bin/hadoop fs -mkdir ./testdata
Warning: $HADOOP_HOME is deprecated.

[huser@master hadoop]$ hadoop-1.2.1/bin/hadoop fs -put ./synthetic_control.data ./testdata
Warning: $HADOOP_HOME is deprecated.

[huser@master hadoop]$ hadoop-1.2.1/bin/hadoop fs -ls ./testdata
Warning: $HADOOP_HOME is deprecated.

-rw-r--r-- 1 huser supergroup 288374 2014-04-17 14:02 /user/huser/testdata/synthetic_control.data

3、做一个kmeans聚类测试

[huser@master hadoop]$ mahout org.apache.mahout.clustering.syntheticcontrol.kmeans.Job

4、观察输出

[huser@master hadoop]$ hadoop-1.2.1/bin/hadoop fs -ls ./output
Warning: $HADOOP_HOME is deprecated.
