question about set up mahout
Hi all,
I'm new to mahout and was trying to set up mahout on my single-node hadoop
cluster (0.20.2).
After following all the instructions on the quick start page, I still got:
11/03/25 18:13:15 WARN driver.MahoutDriver: Unable to add class:
org.apache.mahout.utils.eval.InMemoryFactorizationEvaluator
11/03/25 18:13:16 WARN driver.MahoutDriver: Unable to add class:
org.apache.mahout.utils.eval.ParallelFactorizationEvaluator
11/03/25 18:13:16 WARN driver.MahoutDriver: Unable to add class:
org.apache.mahout.utils.eval.DatasetSplitter
11/03/25 18:13:16 WARN driver.MahoutDriver: No
org.apache.mahout.clustering.syntheticcontrol.dirichlet.Job.props found on
classpath, will use command-line arguments only
11/03/25 18:13:16 INFO dirichlet.Job: Running with default arguments
Where are those classes embedded? I was trying to fix this but no luck.
Thanks a lot,
Steve

Hi Steve,
Check out link for setting up hadoop on single
node(http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/),
if you are using ubuntu system. But I suggest you not to use mahout on
single node, as map-reduce will create more over head, which makes
mahout slow.
Also make sure if Jobtracker, tasktracker are running, all class path are set.
Thanks
Vineet Yadav
