Unknown program 'spark-itemsimilarity' chosen

Question

I have cloudera CDH5 running inside a virtual box.

when I try to run :

mahout spark-itemsimilarity ....

I get the error:

Unknown program 'spark-itemsimilarity' chosen.

Do i have to install any additional package to run the spark-similarity?

Any help would be appreciated !

Answer 1

Spark support for Mahout came from Mahout 0.10 release while you are using 0.9 release. So this should explain why you get the unknown program error. I would suggest using a higher version of Mahout.
