--------------------------------------
Assignee: Paritosh Ranjan
> KMeans failing to create correct Clustering Policy

> Key: MAHOUT-999
> URL: https://issues.apache.org/jira/browse/MAHOUT-999

> Issue Type: Bug
> Reporter: Grant Ingersoll
> Assignee: Paritosh Ranjan
> Priority: Minor

> Jenkins has been complaining about the cluster-reuters.sh example for a while
> and the issue appears to be due to trying to write a file to a directory that
> doesn't exist due to the fact that it is a file, not a directory.
