Hi, I'm a rookie for mahout. Recently when I tried to run ItemSimilarityJob with my own hadoop, I met a problem. The command is: hadoop jar mahout-core-0.9-job.jar org.apache.mahout.cf.taste.hadoop.similarity.item.ItemSimilarityJob -i /home/hadoop/itembased/user_item -o /home/hadoop/itembased/output -s SIMILARITY_EUCLIDEAN_DISTANCE -mp 0 -b true --startPhase 0 --endPhase 0
There are 1 errors: 15/04/10 15:06:02 ERROR common.AbstractJob: Unexpected 0 while processing Job-Specific Options: Unexpected 0 while processing Job-Specific Options: Usage: [--input <input> --output <output> --similarityClassname <similarityClassname> --maxSimilaritiesPerItem <maxSimilaritiesPerItem> --maxPrefs <maxPrefs> --minPrefsPerUser <minPrefsPerUser> --booleanData <booleanData> --threshold <threshold> --randomSeed <randomSeed> --help --tempDir <tempDir> --startPhase <startPhase> --endPhase <endPhase>] What's the resaon for this situation? Thank you! Best Regards, lastarsenal
