Sean Owen resolved MAHOUT-726.
------------------------------
Resolution: Not A Problem
Fix Version/s: (was: 0.6)
OK cool.
> IntWritable / VectorWritable cast problem in classifier/clustering
> implementations

>
> Key: MAHOUT-726
> URL: https://issues.apache.org/jira/browse/MAHOUT-726
> Project: Mahout
> Issue Type: Bug
> Components: Classification, Clustering
> Affects Versions: 0.5
> Reporter: Sean Owen
>
> I think we've seen this sort of error, most recently reported by Hector:
> Exception in thread "main" java.lang.ClassCastException:
> org.apache.hadoop.io.IntWritable cannot be cast to
> org.apache.mahout.math.VectorWritable
> at
> org.apache.mahout.clustering.kmeans.RandomSeedGenerator.buildRandom(RandomSeedGenerator.java:90)
> at
> org.apache.mahout.clustering.kmeans.KMeansDriver.run(KMeansDriver.java:102)
> Hector indicates it's also in LDA and Dirichlet, so probably a common issue
> to all, though also I suspect an easy fix whatever it is.
> Tracking it formally with a JIRA to record the resolution.
