To Whomsoever It May Concern - I have kmeans clusters from Mahout 0.8 version. Since then we have upgraded our Hadoop stack and also Mahout to 0.9 version.
But I wanted to clusterdump the clusters we created using 0.8 version. When I use clusterdump in 0.9 version, I get an error - Exception in thread "main" java.lang.ClassCastException: org.apache.mahout.clustering.classify.WeightedVectorWritable cannot be cast to org.apache.mahout.clustering.classify.WeightedPropertyVectorWritable In 0.9 Apache Mahout Release Notes below, I see that the ClusteredPoints should be weightpropertyvectorwritable and not weightedvectorwritable. http://svn.apache.org/viewvc/mahout/trunk/CHANGELOG?view=markup&pathrev=1563661 What should I do in this case? I still want the clusterdump of my previous clusters developed from 0.8 version. I look forward to your reply. Thank you, V
