is hadoop necessary to run mahout-in-action examples?

is hadoop necessary to run the Mahout In Action examples? i saw that there is a hadoop jar provided with mahout. i have been having problems with build-reuters.sh and was wondering if a seper开发者_StackOverflowate hadoop installation is necessary. thanks!!

Most of the book Mahout in Action concerns using Apache Mahout with Apache Hadoop. So yes, you will end up needing Hadoop. The book directs you to download and install Hadoop.

Hadoop itself is not provided with Mahout, no. However Mahout's build system references Hadoop, so it will automatically download dependencies like Hadoop. This is a different thing.

You have not said what your actual problem is with the script.
