Re:Re: Exception throws when running spark pi in Intellij Idea that scala.collection.Seq is not found

Thanks you guys.
Yes, I have fixed the guava and spark core and scala and jetty. And I can run 
Pi now.

As I remember, you also need to change guava and jetty related dependency to 
compile if you run to run SparkPi in intellij.

Go to the module settings of the project and in the dependencies section check 
the scope of scala jars. It would be either Test or Provided. Change it to 
compile and it should work. Check the following link to understand more about 
scope of modules:

I cloned the code from https://github.com/apache/spark to my machine. It can

But when I run the sparkpi, it throws an exception below complaining the

I have installed scala2.10.4 in my machine, and use the default profiles: 
window,scala2.10,maven-3,test-java-home.
In Idea, I can find that the Seq class is on my classpath:
