Hello,
I am trying to read the output generated by PFPGrowth from another map/reduce
job and I am getting classnot found exception. I even copied mahout jar file to
hadoop's lib folder and still no luck. I am wondering if anyone has this issue.
I also tried with libjars option and that's giving me cannot open file error.
Where should I be putting the mahout's jar file in order to avoid this
exception?
$ hadoop-0.20.2/bin/hadoop jar
/home/ppeddi/dev/Merchandising/RelevancyEngine/relevancy-core/dist/Relevancy4.jar
-i raw-downloads-input-10K -o reco-patterns-output-10K-1S -k 100
-method mapreduce -g 500 -regex '[\ ]' -s 5
