Resolution: Fixed

> Key: MAHOUT-651
> URL: https://issues.apache.org/jira/browse/MAHOUT-651
> Project: Mahout
> Issue Type: Improvement
> Components: Clustering
> Affects Versions: 0.4
> Reporter: Robert Mahfoud
> Assignee: Sean Owen
> Fix For: 0.5

>
> Some classes in the Classification component internally use the hadoop's
> FileSystem class, however, they instantiate the hadoop configuration locally
> in the method using {{new Configuration()}}. This limits the ability to
> integrate these tools within applications that manage and enrich their own
> configuration rather than rely on the default hadoop resources that get
> loaded when calling {{new Configuration()}}.
> The fix is simply to make these methods take a {{Configuration}} parameter
> rather than creating a new instance when needed. An example for an that
> creates a new {{Configuration}} instances is:
> {{org.apache.mahout.clustering.kmeans.KMeansUtil.configureWithClusterInfo(Path,
> List<Cluster>)}}
> This problem could also exists beyond the Clustering module, but this issue
> only addresses the Clustering code.
