1 I don't use spark_submit to run my problem and use spark context directly
val conf = new SparkConf()
.setMaster("spark://123d101suse11sp3:7077")
.setAppName("LBFGS")
.set("spark.executor.memory", "30g")
.set("spark.akka.frameSize","20")
val sc = new SparkContext(conf)
2 I use KDD data, size is about 5G
3 After I execute LBFGS.runLBFGS, at the stage of 7, the problem occus:
[cid:image001.png@01CFB197.A3BD3D60]
