Re: Error when testing with large sparse svm
Then it may be a new issue. Do you mind creating a JIRA to track this issue? It would be great if you can help locate the line in BinaryClassificationMetrics that caused the problem.

Re: Error when testing with large sparse svm
I don't really know how to create JIRA :(
Specifically, the code I commented out are:
//val prediction = model.predict(test.map(_.features))
//val predictionAndLabel = prediction.zip(test.map(_.label))
//val prediction = model.predict(training.map(_.features))
//val predictionAndLabel = prediction.zip(training.map(_.label))
//val metrics = new BinaryClassificationMetrics(predictionAndLabel)
//println(sTest areaUnderPR = ${metrics.areaUnderPR()}.)
//println(sTest areaUnderROC = ${metrics.areaUnderROC()}.)
in
examples/src/main/scala/org/apache/spark/examples/mllib/BinaryClassification.scala.

Re: Error when testing with large sparse svm
I got a bit progress. I think the problem is with the BinaryClassificationMetrics, as long as I comment out all the prediction related metrics, I can run the svm example with my data. So the problem should be there I guess. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/Error-when-testing-with-large-sparse-svm-tp9592p9832.html Sent from the Apache Spark User List mailing list archive at Nabble.com.

Re: Error when testing with large sparse svm
If you use Scala, you can do: val conf = new SparkConf() .setMaster(yarn-client) .setAppName(Logistic regression SGD fixed) .set(spark.akka.frameSize, 100) .setExecutorEnv(SPARK_JAVA_OPTS, -Dspark.akka.frameSize=100) var sc = new SparkContext(conf) I have been struggling with this too. I was trying to run Spark on the KDDB website which has about 29M features. It implodes and dies.
