> --------------------------------------------------------------------------------
>
> Key: SPARK-36603
> URL: https://issues.apache.org/jira/browse/SPARK-36603
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.1.2
> Reporter: Sean R. Owen
> Assignee: Apache Spark
> Priority: Minor
>
> See discussion at https://github.com/apache/spark/pull/28769#issuecomment-906722390
> The SoftReference used to track iterators in LevelDB can prevent them from being GCed early enough, thus finalized and closed. A WeakReference would be more readily collected, and solves an apparent actual issue running a 3.1.x SHS.
