---------------------------------------
Summary: Memory leaks in ParquetColumnVector
Key: SPARK-60098
URL: https://issues.apache.org/jira/browse/SPARK-60098
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.3.0
Reporter: Filipe Oliveira
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.
