----------------------------------
Summary: Option to change RecommenderJob output format
Key: MAHOUT-1352
URL: https://issues.apache.org/jira/browse/MAHOUT-1352
Project: Mahout
Issue Type: New Feature
Components: Collaborative Filtering
Affects Versions: 0.9
Reporter: Pat Ferrel
Fix For: 0.9
Can we add an option to output a SequenceFile? I hard coded it to allow the
Solr-recommender to work with the output file but it is probably best put in an
option.
//extract out the recommendations
Job aggregateAndRecommend = prepareJob(
new Path(aggregateAndRecommendInput), outputPath,
SequenceFileInputFormat.class,
PartialMultiplyMapper.class, VarLongWritable.class,
PrefAndSimilarityColumnWritable.class,
AggregateAndRecommendReducer.class, VarLongWritable.class,
RecommendedItemsWritable.class,
SequenceFileOutputFormat.class); <-- text format in Mahout trunk
Should be able to choose format class from the params.
