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

             Summary: K-Means writes only k records as a output
                 Key: HAMA-821
                 URL: https://issues.apache.org/jira/browse/HAMA-821
             Project: Hama
          Issue Type: Bug
          Components: machine learning
            Reporter: Edward J. Yoon
            Assignee: Edward J. Yoon
             Fix For: 0.7.0


KMeans writes only k records, because 276 line at KMeansBSP overwrites the 
value for the key. I'm sure it was not intended. I'll fix this..

And, make K-Means example output lines more readable (like mahout):

{code}
