Hello,
I am new to Mahout. I have installed the Mahout-0.9.
I have configured a hadoop(1.0.3)) on my laptop (Redhat 6, Lenovo W530). I
am experimenting the k-means test ( by running
mahout-distribution-0.9/examples/bin/cluster-reuters.sh)
I am able to run the k-means test out of box on hadoop in loacal mode
successfully.
However, when I run hadoop in pseudo-distributed mode, the k-means test
would fail (after successfully running 9 Map-Reduce jobs) with following
stacktrace:
Exception in thread "main" java.lang.IllegalStateException: No input
clusters found
in /tmp/mahout-work-weiz/reuters-kmeans-clusters/part-randomSeed. Check
your -c argument.

I tried to google the reason for this failure, but couldn't get a clear
understanding. I am wondering could you help with some pointers ?
Thanks!
