No, it's not something you really install. It's a library. However I think you'll find the binaries already exist on all the nodes in your cluster anyway.

Mahout is already shipped with CDH. It's not something you really install; it's a library. Can you say any more about the problem you are facing?

Hi,
Thank you for your answer.
I added the library mahout but when i type the command : mahout it says:
mahout_local is not set adding hadoop_conf_dir to classpath
How can i set the mahout local variable ?

It's just an env variable; you can always "export VARIABLE=VALUE" in the shell.

But this message is not an error. In fact you want to see this if you intend to run on a cluster.

I want the program to run in Hadoop filesystem. How do I unset MAHOUT_LOCAL
to do so?
