run

public static Job run(Key dest,
                      KMeansModel model,
                      ValueArray ary)

map

public void map(Key key)

Creates a new ValueArray with classes. New ValueArray is not aligned with source one unfortunately so have to send results to each chunk owner using Atomic.

Specified by:

map in class MRTask

reduce

public void reduce(DRemoteTask rt)

Specified by:

reduce in class DRemoteTask
