我试图在本地系统上运行mahout，当我运行“../bin/mahout”时，出现下面提到的错误。我所要做的就是在没有hadoop的情况下运行mahout，并尝试20newsgroup示例。
我在core、distribution和example目录中执行了“mvncomile”和“mvn install-dmaven.test.skip=true”。不知道我还缺什么。我知道你可以在没有hadoop的情况下运行mahout。
如果有人能帮忙，我将不胜感激。

hadoop binary is not in PATH,HADOOP_HOME/bin,HADOOP_PREFIX/bin, running locally
