Yes, that was my point. below It may, in fact, be impossible to
implement and commit them independently since so much of Mahout
clustering depends upon the Cluster sequenceFile. You may be able to get
part way by moving the Canopy mods into the kmeans issue, but then the
cluster dumper and evaluator will not work with kmeans.
Ideas?

Thanks Jeff. One question, are "Use ClusterIterator" tasks dependent
on "Modify Canopy etc to use ClusterWritable" task ?
I am assuming that all subtasks in MAHOUT-933
<https://issues.apache.org/jira/browse/MAHOUT-933> are independent of
each other and the order to pick them does not matter. Am I correct?

Sure Paritosh, go ahead and take a crack at it. I am moving from CO
to PA for the next few weeks and won't be able to do much coding
during that period. I suspect you will also need to modify Canopy to
emit ClusterWritable and also the RandomSeedGenerator.
Smooth sailing,
Jeff

----------------------------------------
Jeff, I would like to work on this issue (or MAHOUT-989, or
MAHOUT-990). Can I? I might also need some help ( at least the first
patch review ).
Convert K-means buildClusters to use new ClusterIterator
--------------------------------------------------------
Key: MAHOUT-988
URL: https://issues.apache.org/jira/browse/MAHOUT-988
Project: Mahout
Issue Type: Sub-task
Components: Clustering
Affects Versions: 0.6
Reporter: Jeff Eastman
Assignee: Jeff Eastman
Fix For: 0.7
Refactor the current K-means implementation to use the
ClusterIterator/Classifier implementation. This will replace the
mapper, combiner, reducer, clusterer and many unit tests but will
not modify the other driver APIs, thus retaining compatibility with
existing CLI.
