> 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.
