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

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.

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 seperate hadoop installation is necessary.

Thanks! Hadoop mahout link|improve this question asked Aug 22 '11 at 11:32aber buch6.

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.

Thanks very much. The script runs fine, after installing maven again. However, there is another issue.

I installed mahout and the hadoop plugin into eclipse. I can read and cluster the reuters data created by the script- very cool. However, when I create the document.

Seq file with a writer (my own example documents), running the same code gives nonsense: 0 belongs to cluster 1.0 for every document. Thanks again for your help. Appreciated!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
