Description

The Solr-recommender needs to find where the RecommenderJob is putting it’s output.

Mahout 0.8 RecommenderJob code was:
public static final String DEFAULT_PREPARE_DIR = "preparePreferenceMatrix”;

Mahout 0.9 RecommenderJob code just puts “preparePreferenceMatrix” inline in the code:
Path prepPath = getTempPath("preparePreferenceMatrix");

This change to Mahout 0.9 works:
public static final String DEFAULT_PREPARE_DIR = "preparePreferenceMatrix”;
and
Path prepPath = getTempPath(DEFAULT_PREPARE_DIR);

You could also make this a getter method on the RecommenderJob Class instead of using a public constant.
