Pat Ferrel commented on MAHOUT-1588:
------------------------------------
Does this work for all recommender CLIs?
The new spark-itemsimilarity already have a flexible method for passing in
multiple directories and files even supporting recursive regex discovery of
input.
This is too large for 0.10.0 and may not be of enough importance to test for
later release.
If the contributor feels this is important, please create a PR and include
tests.

> Now recommendation job can only import a input path via "--input", and can't
> load file from different path. Customers may put preference data in different
> path. This is a very usual scenario.
> I add a option named "--multiInput(-mi)", and don't remove the original input
> option. These two input option can set together. And the modification only
> refer to PreparePreferenceMatrixJob, which load data from filesystem.
