I think you would have to provide more information. What application? what version of CDH4? What error do you get? What have you tried to resolve it?

I think this is still far too little information to provide help. You should supply basic information like:

What is this application? is it a standalone jar or run with hadoop jar?
What have you tried?
What did you do when it worked?
If you get an error, what is the error?
What version of software, etc?

1. The application is a standalone jar.

2. I want to running the app in cdh4.

3. I know how to running the app in single linux. But I don't know how to running on cloudera cdh4 hadoop cluster.

It is not any different than running your application against any other Hadoop cluster, or should not be.

What happens if you run your jar on a Linux machine that can see the Hadoop cluster, and see the configuration for your hadoop cluster? what doesn't work?

In the hadoop clulster the jar runs with the hadoop command "/usr/bin/hadoop jar /root/mahout/himahout.jar".

Only one host computed the jar.

Sorry, your question is not clear at all and I can't help. As I've said, it is not different with CDH. You have not said what your error is when you run the very command you cited.

What can you offer?

You said it is not different with CDH. Would you tell me how to run with cdh?

Yes, that's the same me. Please have a look at the project page for some simple examples to get started: https://github.com/cloudera/oryx There is no Mongo integration per se, but you could always hack on it.
