kmeans is throwing IllegalArgumentException
Hi All,
I am trying to run the following command:
./mahout kmeans -i hdfs://master:54310/user/netlog/upload/output4/tfidf-vectors/part-r-00000 -o hdfs://master:54310//user/netlog/upload/output4/tfidf-vectors-kmeans-clusters-raghuveer -c hdfs://master:54310/user/netlog/upload/output4/uscensus-kmeans-centroids -dm org.apache.mahout.common.distance.CosineDistanceMeasure -x 5 -ow -cl -k 25
getting the following exception:
IllegalStateException: No input clusters found in hdfs://master:54310/user/netlog/upload/output4/uscensus-kmeans-centroids/part-randomSeed. Check your -c argument.
kindly suggest how i can get ride of this exception.
Note : i see a vector in part-r-00000 but why it says "no input" is not clear to me.
regards,.

Yes, that's correct

I think you don’t want to supply a -c argument unless you have seed vectors in /user/netlog/upload/output4/uscensus-kmeans-centroids/part-randomSeed. Just leave it out and Mahout will use random seeds.
