> https://issues.apache.org/jira/browse/SPARK-34863 introduced the
> ParquetColumnVector class and alongside it 2 column vectors:
> `repetitionLevels` and `definitionLevels`. These vectors are allocated by the
> class but never closed.
>
> Meanwhile, other PRs have changed this class and also allocated column
> vectors but did not close them:
> * [https://github.com/apache/spark/pull/52557]
> * [https://github.com/apache/spark/pull/48851]
>
> When using OFF_HEAP mode these vectors will lead to memory leaks.
