1.稀里糊涂下载
我的集群是hadoop 2.7.3 ，本来想找到对应的mahout版本，但是没有找到。本着安全原则，mahout最新版本是0.14.0，回退一个版本使用0.13.0
2.安装后
一波操作：解压到D：Zoo和配置好环境变量后，运行报错！！！
D:\Zoo\apache-mahout-distribution-0.13.0\bin>mahout
"===============DEPRECATION WARNING==============="
"This script is no longer supported for new drivers as of Mahout 0.10.0"
"Mahout's bash script is supported and if someone wants to contribute a fix for this"
"it would be appreciated."
"Mahout home set D:\Zoo\mahout-0.14.0"
"ERROR: Could not find mahout-examples-*.job in D:\Zoo\mahout-0.14.0 or D:\Zoo\mahout-0.14.0/examples/target, please run 'mvn install' to create the .job file"
3.继续修复
查到博客说有用 mvn可以解决这个问题
切换到examples目录下：
mvn -Dhadoop2.version=2.7.3 -DskipTests clean install
