mahout-distribution-0.9.tar.gz的安装的与配置、启动与运行自带的mahout算法

 

 

 　　不多说，直接上干货！

 

　　首先，别在windows下搭建什么，安装什么Cygwin啊！直接在linux，对于企业里推荐用CentOS6.5，在学校里用Ubuntu。

 

 

 

Mahout安装所需软件清单：

软件　　　　　　　　版本　　　　　　　　　　说明

操作系统　　　　CentOS6.5　　　　　　　　64位

JDK　　　　　　jdk1.7.0_79　　　　　　　　

Hadoop　　　　　　2.6.0　　　　　　　　　　

Mahout　　　　　mahout-distribution-0.8    

 

 　　为什么采用这个版本，而不是0.9及其以后的版本，是因为差别有点大，比如fpg关联规则算法。以及网上参考资料少

 

 

 

 

 

　　说在前面的话，

　　关于Mahout的安装配置，这里介绍两种方式：其一，下载源码（直接下载源码或者通过svn下载源码都可以），然后使用Maven进行编译；其二，下载完整包进行解压缩。这里我使用的是完整包进行解压缩安装。

 

 

 

 

 

一、 mahout-distribution-0.8.tar.gz的下载

 

http://archive.apache.org/dist/mahout/0.8/

 

 

 　　我这里，以稳定版本mahout-0.9为例

 

 

 

　　当然，这里也可以使用wget命令在线下载，很简单，不多说。

 

 

 

 

 

 

 


二、 mahout-distribution-0.8.tar.gz的安装

　　1、先新建好目录

　　我一般喜欢在/usr/loca/下新建

 　　2、上传mahout压缩包

[root@djt002 local]# su hadoop
[hadoop@djt002 local]$ cd mahout/
[hadoop@djt002 mahout]$ pwd
/usr/local/mahout
[hadoop@djt002 mahout]$ ll

-rw-r--r-- 1 hadoop hadoop 69248331 Apr  6 16:09 mahout-distribution-0.8.tar.gz
[hadoop@djt002 mahout]$

 

 

 

 

 

 　　3、解压

[hadoop@djt002 mahout]$ pwd
/usr/local/mahout
[hadoop@djt002 mahout]$ ll
total 67628
-rw-r--r-- 1 hadoop hadoop 69248331 Apr  6 16:09 mahout-distribution-0.8.tar.gz
[hadoop@djt002 mahout]$  tar  -zxvf  mahout-distribution-0.9.tar.gz

 

 

 

 

 

 　　4、删除压缩包和赋予用户组

[hadoop@djt002 mahout]$ pwd
/usr/local/mahout
[hadoop@djt002 mahout]$ ll
total 67632
drwxrwxr-x 7 hadoop hadoop     4096 Apr  7 00:25 mahout-distribution-0.8

total 4
drwxrwxr-x 7 hadoop hadoop 4096 Apr  7 00:25 mahout-distribution-0.8
[hadoop@djt002 mahout]$

 

 

 

 　　5、mahout的配置

[root@djt002 mahout-distribution-0.8]# pwd
/usr/local/mahout/mahout-distribution-0.8
[root@djt002 mahout-distribution-0.8]# vim /etc/profile

 

 

 

 

#mahout
export MAHOUT_HOME=/usr/local/mahout/mahout-distribution-0.8
export MAHOUT_HOME_CONF_DIR=/usr/local/mahout/mahout-distribution-0.8/conf
export PATH=$PATH:$MAHOUT_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib:$MAHOUT_HOME/lib:$JRE_HOME/lib:$CLASSPATH

 

 

 

 

[root@djt002 mahout-distribution-0.9]# source /etc/profile

 

 

 　　认识下mahout的目录结构

[hadoop@djt002 mahout-distribution-0.8]$ pwd

[hadoop@djt002 mahout-distribution-0.9]$

　　出现上述的界面，说明mahout安装成功，因为，自动列出mahout已经实现的所有命令。

 

 

 

 

 

运行mahout自带的示例（确保hadoop集群已开启）

 

 

 

 

mahout中的算法大致可以分为三大类：

　　聚类，协同过滤和分类

 

其中

　　常用聚类算法有：canopy聚类，k均值算法（kmeans），模糊k均值，层次聚类，LDA聚类等

　　常用分类算法有：贝叶斯，逻辑回归，支持向量机，感知器，神经网络等

 

 

　　因为，我的版本是mahout-0.8，所以mahout-examples-0.8-job.jar。

 

 

 

　　以下是运行mahout自带的keans算法
$HADOOP_HOME/bin/hadoop  jar  /usr/local/mahout/mahout-distribution-0.8/mahout-examples-0.8-job.jar   org.apache.mahout.clustering.syntheticcontrol.kmeans.Job


　　或者

 　　准备测试数据

练习数据下载地址：

http://download.csdn.net/detail/qq1010885678/8582941

　　上面的练习数据是用来检测kmeans聚类算法的数据。

 

 

 

 

　　将练习数据（data.txt）上传到hdfs中对应的hdfs://djt002:9000/user/hadoop/testdata目录下即可。（这是样本数据集，可以适用各种算法）

 

 

 

 

　　   我这里，上传测试数据。到我本地linux自己写的一个路径。（这里为了自己所需哈）

 

[hadoop@djt002 mahout]$ pwd
/usr/local/mahout
[hadoop@djt002 mahout]$ ll
total 4
drwxrwxr-x 7 hadoop hadoop 4096 Apr  7 00:25 mahout-distribution-0.8

[hadoop@djt002 mahoutData]$

 

 

 

 

 　　然后，将/usr/local/mahout/mahoutData/下的测试数据，上传到hdfs://djt002:9000/user/hadoop/testdata下

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop fs -put /usr/local/mahout/mahoutData/data.txt  hdfs://djt002:9000/user/hadoop/testdata

或者

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop fs -copyFromLocal  /usr/local/mahout/mahoutData/data.txt  hdfs://djt002:9000/user/hadoop/testdata/



[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop fs -ls hdfs://djt002:9000/user/hadoop/testdata/
-rw-r--r--   1 hadoop supergroup     288972 2017-04-28 07:02 hdfs://djt002:9000/user/hadoop/testdata

 

 

 

 

　　也许中间会出现，这个数据集，你会上传不了。解决方案如下

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop fs -put /usr/local/mahout/mahoutData/data.txt  hdfs://djt002:9000/user/hadoop/testdata/
put: `hdfs://djt002:9000/user/hadoop/testdata': File exists
[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop fs -rm   hdfs://djt002:9000/user/hadoop/testdata/
17/04/28 07:16:58 INFO fs.TrashPolicyDefault: Namenode trash configuration: Deletion interval = 0 minutes, Emptier interval = 0 minutes.

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop fs -mkdir   hdfs://djt002:9000/user/hadoop/testdata/
[hadoop@djt002 mahoutData]$

 

 

 

 

 

 

 

 

 

 

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop fs -put /usr/local/mahout/mahoutData/data.txt  hdfs://djt002:9000/user/hadoop/testdata/
[hadoop@djt002 mahoutData]$

 

 

 

 

 

 

 

 

使用kmeans算法

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop  jar  /usr/local/mahout/mahout-distribution-0.8/mahout-examples-0.8-job.jar   org.apache.mahout.clustering.syntheticcontrol.kmeans.Job

　　注意，是不需输入路径和输出路径的啊!（自带的jar包里都已经写死了的）

　　（注意：如果你是选择用mahout压缩包里自带的kmeans算法的话，则它的输入路径是testdata是固定死的，

　　　　　　　　即hdfs:djt002://9000/user/hadoop/testdata/  ）

　　并且每次运行hadoop都要删掉原来的output目录！

 

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop fs -rm -r hdfs://djt002:9000/user/hadoop/output/*

 

 

 

　　....

　　由于聚类算法是一种迭代的过程（之后会讲解）

　　所以，它会一直重复的执行mr任务到符合要求（这其中的过程可能有点久。。。）

 

 

 

 

 

 

 

 

Kmeans运行结果如下：

70, 7.311, 10.611, 6.924, 3.440, 9.465, 4.764, 2.838, 8.807, 1.960, 2.864, 6.728, 0.369, 1.374, -0.167, 2.125, 8.306, 4.908, -0.432]

　　mahout无异常！！！

 

 

　　注意：执行完这个kmeans算法之后产生的文件按普通方式是查看不了的，看到的只是一堆莫名其妙的数据！！！

　　查看聚类分析的结果：

　　需要用mahout的seqdumper命令来下载到本地linux上才能查看正常结果。

 　　当然，你可以去看输出目录下/user/hadoop/output的其他的，比如clusters-0、clusters-1等，我这里仅仅是

看的是/user/hadoop/output/data/下的。

 

 

 

 

 

 

 

 

使用canopy算法

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop  jar  /usr/local/mahout/mahout-distribution-0.8/mahout-examples-0.8-job.jar   org.apache.mahout.clustering.syntheticcontrol.canopy.Job

 　　这里不多赘述。



使用dirichlet 算法

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop  jar  /usr/local/mahout/mahout-distribution-0.8/mahout-examples-0.8-job.jar   org.apache.mahout.clustering.syntheticcontrol.dirichlet.Job

 　　这里不多赘述。

 


使用meanshift算法

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop  jar  /usr/local/mahout/mahout-distribution-0.8/mahout-examples-0.8-job.jar   org.apache.mahout.clustering.syntheticcontrol.meanshift.Job

 　　这里不多赘述。

 

 

 

 

 

 

 总结

　　mahout压缩包，给我们的默认输入路径是/user/hadoop/testdata  和  输出路径是 /user/hadoop/output  

　　其实，我们是自己可以跟上自定义的输入路径和自定义输出路径的。

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop  jar  /usr/local/mahout/mahout-distribution-0.8/mahout-examples-0.8-job.jar   org.apache.mahout.clustering.syntheticcontrol.kmeans.Job

 

 

[hadoop@djt002 mahoutData]$ $HADOOP_HOME/bin/hadoop  jar  /usr/local/mahout/mahout-distribution-0.8/mahout-examples-0.8-job.jar   org.apache.mahout.clustering.syntheticcontrol.kmeans.Job   -i   /user/hadoop/mahoutData/data.txt   -o  /user/hadoop/output
