问题
I am trying to cluster a sample dataset which is in csv file format. But when I give the below command,
user@ubuntu:/usr/local/mahout/trunk$ bin/mahout kmeans -i /root/Mahout/temp/parsedtext-seqdir-sparse-kmeans/tfidf-vectors/ -c /root/Mahout/temp/parsedtext-kmeans-clusters -o /root/Mahout/reuters21578/root/Mahout/temp/parsedtext-kmeans -dm org.apache.mahout.common.distance.CosineDistanceMeasure -x 2 -k 1 -ow --clustering -cl
I am getting the following error, saying there is no input clusters available and to check the -c cluster argument. Can anybody help me please>
Here is the error which I got for the above command:
16/05/11 16:09:15 INFO compress.CodecPool: Got brand-new decompressor [.deflate]
Exception in thread "main" java.lang.IllegalStateException: No input clusters found in /root/Mahout/temp/parsedtext-kmeans-clusters/part-randomSeed. Check your -c argument.

Let me copy the error message for you:
No input clusters found in /root/Mahout/temp/parsedtext-kmeans-clusters/part-randomSeed. Check your -c argument.
Have you considered checking or removing your -c argument?
But Mahout k-means is really low-quality. Use something else. apt-get install elki and try that instead, it's much faster.
