[jira] [Created] (SPARK-7100) GradientBoostTrees leaks a persisted RDD

Jim Carroll created SPARK-7100:
----------------------------------

             Summary: GradientBoostTrees leaks a persisted RDD
                 Key: SPARK-7100
                 URL: https://issues.apache.org/jira/browse/SPARK-7100
             Project: Spark
          Issue Type: Bug
          Components: MLlib
    Affects Versions: 1.3.1, 1.2.2
            Reporter: Jim Carroll
             Fix For: 1.4.0


It appears GradientBoostedTrees.scala can call 'persist' on an RDD and never unpersist it.

In the master branch it's in GradientBoostedTrees.boost method. It "persists" the input RDD if it's not already persisted but doesn't unpersist it.

I'll be submitting a PR with a fix.
