[https://github.com/HeartSaVioR/spark/commit/4555a595f8fe2ebeaae8018c31a905697e5bdb3c]

> Removing block is not reflected to the driver/executor's storage memory
> -----------------------------------------------------------------------

>                 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.
