When I try to include GraphX into my work, it seems I'm doing something wrong because Scala IDE doesn't recognize org.apache.spark.graphx._
or anything related to graphs (!)
Did I miss something when I first created my project? Do I need to include additional libraries (how?)?
You need to add the GraphX dependency to your pom file.
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-graphx_2.10</artifactId>
<version>1.6.1</version>
</dependency>
