----------------------------------

Sounds good, have you verified this by testing it out? that it recurs properly with this change?

> The org.apache.mahout.text.PrefixAdditionFilter is not working as intended. The prefix is computed wrong when there is recursion (this is when there is at least one subdirectory).
> I think the line:
> fs.listStatus(fst.getPath(), new PrefixAdditionFilter(getConf(), getPrefix() + Path.SEPARATOR + current.getName(), getOptions(), writer, fs));
> should better be:
> fs.listStatus(fst.getPath(), new PrefixAdditionFilter(getConf(), getPrefix() + Path.SEPARATOR + current.getName() + Path.SEPARATOR + fst.getPath().getName(), getOptions(), writer, fs));
