在http://archive.apache.org/dist/mahout下载相应版本的mahout 版本，获取官网查看http://mahout.apache.org 相关的信息
下载后解压，
tar -zxvf mahout-distribution-0.9.tar.gz
配置环境变量
export MAHOUT_HOME=/home/sms/mahout-distribution-0.9 export MAHOUT_CONF_DIR=$MAHOUT_HOME/conf export PATH=$MAHOUT_HOME/bin:$PATH export CLASSPATH=$CLASSPATH:$MAHOUT_HOME/lib:$MAHOUT_HOME/lib/hadoop/hadoop-core-1.2.1.jar export MAHOUT_LOCAL=
2 启动hadoop运行测试
下载测试数据 http://archive.ics.uci.edu/ml/databases/synthetic_control/synthetic_control.data 创建测试目录 testdata，并把数据导入到这个tastdata目录中(这里的目录的名字只能是testdata) hadoop fs -mkdir testdata hadoop fs -put synthetic_control.data testdata 命令测试 hadoop jar /home/sms/mahout-distribution-0.9/mahout-examples-0.9-job.jar org.apache.mahout.clustering.syntheticcontrol.kmeans.Job 命令查看 hadoop fs -ls output

MAHOUT_LOCAL is not set; adding HADOOP_CONF_DIR to classpath.
Running on hadoop, using HADOOP_HOME=/home/sms/hadoop
HADOOP_CONF_DIR=/home/sms/hadoop/etc/hadoop
MAHOUT-JOB: /home/sms/mahout-distribution-0.6/mahout-examples-0.6-job.jar
Exception in thread "main" java.lang.NoSuchMethodError: org.apache.hadoop.util.ProgramDriver.driver([Ljava/lang/String;)V

还没有答案？目前倾向于hadoop与mahout版本冲突造成的。
