Hi Xiangrui, According to my knowledge, calling count is for materialize the RDD, does collect do the same thing since it also an action? I can not call count because for a Graph object, count does not materialize the RDD. I already send an issue on that.
My question is, why there still have stack overflow even if `isCheckpointed` is true? -- View this message in context: http://apache-spark-developers-list.1001551.n3.nabble.com/Checkpointed-RDD-still-causing-StackOverflow-tp7066p7068.html Sent from the Apache Spark Developers List mailing list archive at Nabble.com.
