Not sure as to where this is coming from, the code is all new M/R APIs AFAIK.
How/Who invokes OldMapper in a MapReduce job?

> Here is a lucene2seq tool I used in a project. It creates sequence files
> based on the stored fields of a lucene index.
> The output from this tool can be then fed into seq2sparse and from there you
> can do text clustering.
> Comes with Java bean configuration.
> Let me know what you think. Some CLI code can be added later on. I used this
> for a small-scale project +- 100.000 docs. Is a MR version useful or is that
> overkill?
> See https://github.com/frankscholten/mahout/tree/lucene2seq for commits and
> review comments from Simon Willnauer (Thanks Simon!)
> or the attached patch.
