.props files for bin/mahout

[Sebastian Schelter <ss...@apache.org>]

Hi,

Short question as I couldn't figure it out with a brief look at the code.

What's the use of adding a *.props file to conf/ after I've added a new
line to conf/driver.classes.props? All existing .props files seem to be
empty or have all their content commented out.

Should empty .props files also be added for rowsimilarity,
itemsimilarity and recommenditembased (these exist in
driver.classes.props but do not have another props file of their own yet)?

They are meant to be used by end users so that they can store their settings.  So, they are just placeholders.
