I am trying to use mahout for spark and followed the instruction below: https://mahout.apache.org/users/sparkbindings/play-with-shell.html
I have successfully installed oracle-7-java, maven 3.3.9. Instead of spark 1.1.0 I have downloaded spark 2.0.1 and ran build/sbt assembly which took care of scala (install 2.11.8) and other dependencies. I have also installed git, and checked out latest version of mahout in /home/mehrab/mahout-src directory.
Spark is running well and fine without any error. Mahout is also built successfully without any error. After running spark and taking the master url, I have set JAVA_HOME, SPARK_HOME, MAHOUT_HOME, MASTER.
So meeting all requirement when I finally try to launch mahout shell by running bin/mahout spark-shell it gives me following error:
mehrab@ubuntu:~/mahout-src$ bin/mahout spark-shell
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/repl/SparkILoop

Can anyone help? Thanks in advance.
