>             Project: Mahout
>          Issue Type: Bug
>          Components: Algorithms, Collaborative Filtering, Documentation
>    Affects Versions: 0.14.0, 0.13.2

> Seems like newer versions of Mahout do have problems with spark bindings e.g. mahout spark-itemsimilarity or mahout spark-rowsimilarity do not work due to class not found exceptions. 
> {code:java}
> Error: Could not find or load main class org.apache.mahout.drivers.RowSimilarityDriver
> {code}
> {code:java}
> Error: Could not find or load main class org.apache.mahout.drivers.ItemSimilarityDriver
> {code}
> whereas *mahout spark-shell* works flawlessly.
