Can add one parameter --itemsFile for
org.apache.mahout.cf.taste.hadoop.item.RecommenderJob ?
--itemsFile some likes the the --usersFile.
in some case, we want to calculate similarity using all preferences data ,
but some item in preferences are old ,not available,behind the times or
retired ,
we want that those data can not recommend to users, can only recommend user
with new or valid items.
so we can add on paramete --itemsFile for RecommenderJob, itemsFile includes
all the new valid items.
