Smita Wadhwa commented on MAHOUT-1080:
--------------------------------------
I have created a WeightedTextVectorWritable(vector,distance-from-the-centre,
vectorId) to hold the output having vectorId as text . I have made it text for
future use if its int/double or text - we can output as text.
PFA the patch for this fix having output vectorId given in the input. Updated
the test cases and verified the output with unit test cases as well on haddop
cluster.
The changes are done for both sequential and MR job both.
> Kmeans clustered output losses vectorId given in the input

> Project: Mahout
> Issue Type: Improvement
> Components: Clustering

> The input to the Kmeans is Intwritable and vectorWritable
> and the output of clustered points is clusterId
> WeightedVectorWitable(vector,distance-from-the-centre)
> The information the id of the vector is lost in this processing .
