> ----------------------------------------------------
>
> Key: SPARK-10182
> URL: https://issues.apache.org/jira/browse/SPARK-10182
> Project: Spark
> Issue Type: Bug
> Components: MLlib
> Affects Versions: 1.4.1
> Reporter: Vyacheslav Baranov
>
> The problem might be reproduced in spark-shell with following code snippet:
> {code}
> import org.apache.spark.SparkContext
> import org.apache.spark.mllib.classification.LogisticRegressionWithLBFGS
> import org.apache.spark.mllib.linalg.Vectors
> import org.apache.spark.mllib.regression.LabeledPoint
> val samples = Seq[LabeledPoint](
> LabeledPoint(1.0, Vectors.dense(1.0, 0.0)),
> LabeledPoint(1.0, Vectors.dense(0.0, 1.0)),
> LabeledPoint(0.0, Vectors.dense(1.0, 1.0)),
> LabeledPoint(0.0, Vectors.dense(0.0, 0.0))
> )
> val rdd = sc.parallelize(samples)
> for (i <- 0 until 10) {
> val model = {
> new LogisticRegressionWithLBFGS()
> .setNumClasses(2)
> .run(rdd)
> .clearThreshold()
> }
> }
> {code}
> After code execution there are 10 {{MapPartitionsRDD}} objects on "Storage"
> tab in Spark application UI.
