Subject [jira] [Created] (SPARK-5499) iterative computing with 1000 iterations causes stage failure
Date Fri, 30 Jan 2015 13:05:34 GMT
Tien-Dung LE created SPARK-5499:
-----------------------------------

             Summary: iterative computing with 1000 iterations causes stage failure
                 Key: SPARK-5499
                 URL: https://issues.apache.org/jira/browse/SPARK-5499
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.2.0
            Reporter: Tien-Dung LE


I got an error "org.apache.spark.SparkException: Job aborted due to stage failure: Task serialization
failed: java.lang.StackOverflowError" when executing an action with 1000 transformations cause.

Here is a code snippet to re-produce the error:

  import org.apache.spark.rdd.RDD
  var pair: RDD[(Long,Long)] = sc.parallelize(Array((1L,2L)))
    var newPair: RDD[(Long,Long)] = null

    for (i <- 1 to 1000) {
      newPair = pair.map(_.swap)
      pair = newPair
    }

    println("Count = " + pair.count())
