Pallavi Palleti commented on MAHOUT-99:
---------------------------------------
I have used KeyValueLineRecordReader internally for my code and forgot to
revert back to SequenceFileReader. Will that be sufficient to add another patch
on the latest code and modify only KMeansDriver to use SequenceFileReader?
Kindly let me know.
Thanks

> Improved the speed of KMeans by passing only cluster ID from mapper to
> reducer. Previously, whole Cluster Info as formatted s`tring was being sent.
> Also removed the implicit assumption of Combiner runs only once approach and
> the code is modified accordingly so that it won't create a bug when combiner
> runs zero or more than once.
