Vertices that aren't connected to anything are perfectly valid e.g. import org.apache.spark.graphx._
val vertices = sc.makeRDD(Seq((1L,1),(2L,1),(3L,1))) val edges = sc.makeRDD(Seq(Edge(1L,2L,1))) val g = Graph(vertices, edges) g.vertices.count gives 3 Not sure why vertices appear to be dropping off. Could you show your full code. g.degrees.count gives 2 - as the scaladocs mention 'The degree of each vertex in the graph. @note Vertices with no edges are not returned in the resulting RDD' ----- Robin East Spark GraphX in Action Michael Malak and Robin East Manning Publications Co. http://www.manning.com/books/spark-graphx-in-action -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/GraphX-create-graph-with-multiple-node-attributes-tp24827p24831.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
