Hello,

I am using Mahout-0.3 to try out various clustering algorithms provided by =
mahout.
I ran arff converter, kmeans and canopy clustering over my data and used cl=
usterdumper to check out the clusters.
For big file sizes or big data to be clustered and interpreted, the output =
of clusterdumper needs some kind of visualization.
So, I read https://cwiki.apache.org/confluence/display/MAHOUT/Visualizing+S=
ample+Clusters
I was able to generate a sample cluster using DisplayClustering class, but =
none other display classes are working for me. I am pasting the error below=
.
Besides, are there any other ways to visualize the output from my data?
How will I feed clusters for my data into these classes in display package?
Please point me to any source of information for the same. Thank you.
