Hey Vaghawan , Thanks for the reply. I was using the ActioML Amazon Droplet and maybe this caused the error. I worked this weekend on setting up my own system and getting stocked at the same step but with a different error.

I used the same sample data as you and the same template.

“Exception in thread “main” java.lang.AssertionError: User data is empty”

If i check the pio.log file I also can see:

WARN: environment variable MYSQL_JDBC_DRIVER is pointing to a nonexistent file /users/sebastian/Development/Recommendation/PredictionIO-0.11.0-incubating/lib/mysql-connector-java-5.1.41.jar. Ignoring.

INFO:No ‘name’ is found. Default empty String will be used.

Any suggestions?
