>                 Key: SPARK-29301
>                 URL: https://issues.apache.org/jira/browse/SPARK-29301
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 2.4.4, 3.0.0
>            Reporter: Jungtaek Lim
>            Priority: Major
>
> While investigating SPARK-29055 I've found that heap memory in driver doesn't increase which would denote memory leak happen, but storage memory doesn't decrease even there're some broadcast blocks getting removed - these values keep increasing.
> Please refer SPARK-29055 to see the step to reproduce. Very easy to see it, as running simple query repeatedly would reproduce the issue.
