Hello everybody, Do you know how can I get the MSE of the clusters in mahout K-Means? I would like to check the quality of the clusters. Thanks!

Debugging mahout K-means CIMapper and CIReducer - Breakpoints disable

Hello everybody, When i was debugging the MapReduce kmeans implementation of mahout, I was not able to put breakpoints to the CIMapper and CIReducer classes, has someone experienced this before? Only for those classes, I am having problems to put breakpoints and I have the sources files... So I

Hello everybody, I am new to this mapReduce and mahout and I have been revising the code in the past few days of the mapReduce implementation of mahout K-Means and there are things that I still do not understand. For example: In the CIMapper we have three main functions: Setup() Map() Cleanup
