Geeting error while ruuning RecommenderJob on hadoop(Recommmendation on hadoop)

After successfully building mahout-core-0.7-SNAPSHOT-job.jar using "mvn
clean package".

hduser@ubuntu: /usr/local/hadoop$ bin/hadoop jar
/opt/mahout/core/target/mahout-core-0.7-SNAPSHOT-job.jar
org.apache.mahout.cf.taste.hadoop.item.RecommenderJob
-Dmapred.input.dir=input/input.txt  -Dmapred.output.dir=output --usersFile
input/users.txt --booleanData

I got the following error:

*ERROR common.AbstractJob: Missing required option --similarityClassname*

i have already seen

[image: extended by]*org.apache.mahout.common.AbstractJob class.


*
There is no problem in syntax.
Not getting what to do to come out?
*
