------------------------------------------------

Summary: Kmeans - java.lang.IllegalStateException: No input clusters found..... Check your -c argument
Key: MAHOUT-1871
URL: https://issues.apache.org/jira/browse/MAHOUT-1871
Project: Mahout
Issue Type: Question
Components: Clustering
Affects Versions: 0.12.1
Environment: S.O. Centos 6.5
hadoop 2.7.2

Reporter: Juan Carlos Sipan Robles
Priority: Critical
Fix For: 0.12.1

By using the kmeans with the following parameters gives the following error.

16/06/12 17:35:43 INFO KMeansDriver: convergence: 0.5 max Iterations: 10
16/06/12 17:35:43 INFO CodecPool: Got brand-new decompressor [.deflate]
Exception in thread "main" java.lang.IllegalStateException: No input clusters found in /mdb/clustered_data/part-randomSeed. Check your -c argument.

Suneel Marthi resolved MAHOUT-1871.
-----------------------------------
Resolution: Not A Bug

U need to provide initial centroids - IIRC u can either provide the initial centroids or provide a folder with -c option to generate random initial centroids . You may want to check the examples/bin/cluster-reuters.sh KMeans to see how its being done.
