Hi all, While trying to run the example from https://cwiki.apache.org/confluence/display/MAHOUT/Itembased+Collaborative+Filtering
With the following command bin/mahout org.apache.mahout.cf.taste.hadoop.item.RecommenderJob --output useroutput -n 10 --usersFile users_test.txt -s SIMILARITY_PEARSON_CORRELATION --input userdata/ I keep getting this error: Exception in thread "main" org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: userdata/ I've tried all kinds of path combinations, still same error. Another weird thing is if I put --input userdata/ as the first argument I get Unexpected usage: <command> [Generic Options] [Job-Specific Options] I'm obviously missing something, so any help would be appreciated. /Alan -- *************************************** M.Sc.(Eng.)
