Scalding tutorial: java.lang.ClassNotFoundException - scala

Question

Please help to run Scalding tutorial.
I have Hadoop 2.2 running on a single node and trying to run Scalding tutorial:
https://github.com/Cascading/scalding-tutorial/
After successfuly buiding 'fat jar' with these commands:
$ git clone git://github.com/Cascading/scalding-tutorial.git
$ cd scalding-tutorial
$ sbt assembly
I try to run tutorial examples as suggested with this command:
$ yarn jar target/scalding-tutorial-0.8.11.jar <TutorialPart> --local <addtional arguments>
Both --local and --hdfs fail with java.lang.ClassNotFoundException:
$ yarn jar target/scala-2.9.3/scalding-assembly-0.10.0.jar 1 --local
Exception in thread "main" java.lang.ClassNotFoundException: 1

Update
Changing command argument to 'Tutorial1', 'Tutorial0' does not help either:
$ yarn jar target/scala-2.9.3/scalding-assembly-0.10.0.jar Tutorial1 --local
Exception in thread "main" java.lang.ClassNotFoundException: Tutorial1

Answer 1

You are passing a wrong name for the main class, that is why it can't find it. It should be Tutorial1 instead of just 1. You can see the error in the stack trace:
Exception in thread "main" java.lang.ClassNotFoundException: 1
There is no class called 1. Try:
$ yarn jar target/scala-2.9.3/scalding-assembly-0.10.0.jar Tutorial1 --local
EDIT: it works just fine to me with this command:
$ yarn jar target/scalding-tutorial-0.8.11.jar Tutorial1 --local
