这是一个愚蠢的问题，但必须有人问。
我已经尝试在本地运行 Mahout，这很有效。现在，我希望由远程集群执行工作，而不是我的本地机器。
那么，我应该在 Hadoop 机器上部署 Mahout 代码，还是仍然可以在本地机器接口上使用 Hadoop 远程制作 Mahout？

No, you don't install Hadoop programs on the Hadoop workers yourself. That would be a nightmare to maintain. Hadoop does it for you when you provide it the JAR file with all code via hadoop jar.
What runs on your local machine, when you run Mahout or anything else Hadoop-based, is a client program that uses Hadoop code to send info to a cluster to start work. That cluster might be local, or remote -- makes no difference to how you run the client, just what the client talks to.
