Why do you have maven.glassfish.org in your repo path?

I would imagine optimizing Mahout jobs are not fundamentally different from
optiimizing any Hadoop job. Make sure you have optimal amount of task per
node configured, as well as optimal amount of memory to prevent GC
thrashing. (Iterative Mahout batches tend to create GC churn at somewhat

I am running kmeans algorithm.
Increasing the number of tasktrackers and datanodes, increase the speed?
Thank you

Did you set -Dmapred.reduce.tasks ? it defaults to 1.

No, as is the default

That means you are having Hadoop run at most 1 reducer at a time across the
whole cluster. In any Hadoop job this needs to be set to about the number
of open reduce slots.

Thanks, Sean.
So I added the line:
MAHOUT_OPTS="$MAHOUT_OPTS -Dmapred.fairscheduler.pool=si.highpri_pipelines"
to $MAHOUT_HOME/bin/mahout and then issued
$MAHOUT_HOME/bin/mahout
org.apache.mahout.clustering.syntheticcontrol.kmeans.Job
but I still ended up with the same error. Moreover, I am st
If you want k-means speed see the new k-means code:

Can you describe your data a bit?

I do not. No idea why it is going there.
I removed .m2 and everything downloaded correctly. But now, I have the slf4j
bindings problem mentioned in another email.
