Sean Owen commented on MAHOUT-324:
----------------------------------
Agree, they don't match. Unless anyone chimes in on this I'm going to fix the
driver to reference Text as the output type.
> conf.setMapOutputValueClass(vectorClass) should be
> conf.setMapOutputValueClass(Text.class); in KMeansDrive.runClustering(...)

> Key: MAHOUT-324
> URL: https://issues.apache.org/jira/browse/MAHOUT-324
> Project: Mahout
> Issue Type: Bug
> Components: Clustering
> Affects Versions: 0.2
> Reporter: William Wallace
> Priority: Minor
>
> It looks to me the MapOutputValueClass is not set correctly in the method
> KMeansDrive.runClustering(...). , which doesn't match the OutputCollector
> used by the KMeansClusterMapper. Although it doesn't affect the output in the
> current implementation since the mapred.reduce.tasks is set to 0, it should
> be corrected.
> Please confirm if this bug is valid.
> Thanks.
