It works fine when we initialise the initial clusters to already existing clusters. In my case, i had taken the clusters from k means algorithm. It seems, this is the same problem which you had mentioned!.

This may be something else though... Can you run it if you point it at existing starting clusters? That way we'd be able to see if its the same problem. -Kate On Sun, Aug 14, 2011 at 9:43 AM, sri krishna <[email protected]> wrote: > Version used: Mahout 0.5 > > Command Runned: > > > bin/mahout fkmeans -i reuters-vectors/tfidf-vectors -c > reuters-kmeans-clusters -o reuters-fkmeans-clusters -cd 1.0 -k 21 -m 2 -ow -x > 10 -dm org.apache.mahout.common.distance.SquaredEuclideanDistanceMeasure > > > > Exception in thread "main" java.lang.NumberFormatException: null > at java.lang.Integer.parseInt(Integer.java:443) > at java.lang.Integer.parseInt(Integer.java:514) > at > org.apache.mahout.clustering.fuzzykmeans.FuzzyKMeansDriver.run(FuzzyKMeansDriver.java:115) > at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) > at > org.apache.mahout.clustering.fuzzykmeans.FuzzyKMeansDriver.main(FuzzyKMeansDriver.java:65) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:616) > at > org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(ProgramDriver.java:68) > at org.apache.hadoop.util.ProgramDriver.driver(ProgramDriver.java:139) > at org.apache.mahout.driver.MahoutDriver.main(MahoutDriver.java:187) > > am i missing anything here??.
