我正在研究社交网络分析项目，我发现使用 Sparkling-graph 可能会非常有帮助。因此，我添加了包含所有依赖项的库到spark主目录。 然后，我试着用一个简单的例子来测试它，如下所示：
import org.apache.spark.SparkContext
import org.apache.spark.graphx.{Graph, VertexRDD}
import ml.sparkling.graph.generators.ring.{RingGenerator, RingGeneratorConfiguration}
import ml.sparkling.graph.operators.OperatorsDSL._
import ml.sparkling.graph.api.operators.measures.VertexMeasureConfiguration
implicit val ctx:SparkContext= sc
val graph =RingGenerator.generate(RingGeneratorConfiguration(numberOfNodes=5))
val centralityGraph: Graph[(Int,Int), _] = graph.degreeCentrality()
centralityGraph.vertices.foreach(println)
不幸的是，我收到了这个错误：
org.apache.spark.SparkException: Job aborted due to stage failure: Task 5 in stage 69.0 failed 4 times, most recent failure: Lost task 5.3 in stage 69.0 (TID 1749, hdp1node2, executor 2): java.lang.ClassCastException: cannot assign instance of scala.collection.immutable.List$SerializationProxy to field org.apache.spark.rdd.RDD.org$apache$spark$rdd$RDD$$dependencies_ of type scala.collection.Seq in instance of org.apache.spark.rdd.MapPartitionsRDD

更多信息：我正在使用Zeppelin，Scala版本2.11.8，master：Yarn，deploy-mode：client处理Spark 2.2.0。 我的平台包含4个节点，每个节点上有一个集群。 P.S：此代码在使用master：local [*]
的spark-shell上正常工作
