Re: SparkPi is geting java.lang.NoClassDefFoundError: scala/collection/Seq
Yeah, lots of libraries needs to be changed to compile in order to run the examples in intellij.

As I remember, you also need to change guava and jetty related library to compile too.

Check module example's dependency (right click examples and click Open Modules Settings), by default scala-library is provided, you need to change it to compile to run SparkPi in Intellij. As I remember, you also need to change guava and jetty related library to compile too.
