> Key: MAHOUT-1141
> URL: https://issues.apache.org/jira/browse/MAHOUT-1141
> Project: Mahout
> Issue Type: Bug
> Components: Clustering
> Affects Versions: 0.7, 0.8
> Environment: MacOS 10.8, Java 7
> Reporter: Samar Lotia
> Priority: Minor
>
> The driver for cvb0_local does not seem to verify whether the caller has
> specified the required maxIterations command line parameter. This results in
> an exception much further down which pretty much requires looking at the
> source to discover the source of the error.
> Exception in thread "main" java.lang.ClassCastException: java.lang.Integer
> cannot be cast to java.lang.String
