Mahout-0.9配置

一：Mahout配置

1、下载mahout-0.9

sudo wget https://archive.apache.org/dist/mahout/0.9/mahout-distribution-0.9.tar.gz

2、解压并修改文件名

sudo tar -zxvf mahout-distribution-0.9.tar.gz

sudo mv mahout-distribution-0.9 mahout

3、配置环境变量

sudo vim /etc/profile

export MAHOUT_HOME=/usr/local/mahout
export MAHOUT_CONF_DIR=$MAHOUT_HOME/conf

重新编译配置文件

source /etc/profile

4、环境测试,如下

mahout

二：算法测试

1、获取测试数据

wget http://archive.ics.uci.edu/ml/databases/synthetic_control/synthetic_control.data

2、上传hadoop集群

hadoop fs -mkdir testdata
hadoop fs -put synthetic_control.data testdata

3、测试算法

cd /usr/local/mahout/
# canopy
hadoop jar mahout-examples-0.9-job.jar org.apache.mahout.clustering.syntheticcontrol.canopy.Job
# kmeans
hadoop jar mahout-examples-0.9-job.jar org.apache.mahout.clustering.syntheticcontrol.kmeans.Job
