> Remove a mapreduce job from parallel FPGrowth workflow
> ------------------------------------------------------
>
> Key: MAHOUT-920
> URL: https://issues.apache.org/jira/browse/MAHOUT-920
> Project: Mahout
> Issue Type: Improvement
> Components: Frequent Itemset/Association Rule Mining
> Affects Versions: 0.6
> Reporter: tom pierce
> Assignee: Robin Anil
> Priority: Minor
> Attachments: MAHOUT-890.patch, MAHOUT-920.patch

> The transaction sorting job could have been made map-only, and another
> mapreduce job follows, so it made sense to combine them. It would have been
> possible to use a ChainMapper approach, but it seemed simpler to fold the
> functionality into the following mapper (ParallelFPGrowthMapper). The
> attached patch does just that.
