Using ItemSimilarity.scala from Java

Hi all,

Trying out the new spark-itemsimilarity code, but I am new to Scala and
have hard time calling certain methods from Java.

Here is a Gist with a Java main that runs the cooccurrence analysis:

When I run this I get an exception:

Exception in thread "main" java.lang.NoSuchMethodError:
org.apache.mahout.drivers.TextDelimitedIndexedDatasetReader.readElementsFrom(Ljava/lang/String;Lcom/google/common/collect/BiMap;)Lorg/apache/mahout/drivers/IndexedDataset;

What do I have to do here to use the Scala readers from Java?

Cheers,

Frank
