> Key: SPARK-25380
> URL: https://issues.apache.org/jira/browse/SPARK-25380
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.1
> Environment: Spark 2.3.1 (AWS emr-5.16.0)
>
> Reporter: Michael Spector
> Priority: Minor

> When debugging an OOM exception during long run of a Spark application (many iterations of the same code) I've found that generated plans occupy most of the driver memory. I'm not sure whether this is a memory leak or not, but it would be helpful if old plans could be purged from memory anyways.
