Buffers allocated by ParquetFileReader.readVectored() are not being released

Commencez par TestParquetReader.java autour de closeAllocator et de la trace de la pile de readVectored, puis examinez le chemin de ParquetFileReader.readVectored() et l’utilisation de TrackingByteBufferAllocator. Reproduisez le problème avec mvn -Dtest=TestParquetReader -Dhadoop.version=3.4.1 ; c’est terminé lorsque le test réussit sans buffers qui fuient avec Hadoop 3.4.0 ou une version ultérieure.

Describe the bug, including details regarding any error messages, version, and platform.

this surfaces when running TestParquetReader with hadoop >= 3.4.0

mvn -Dtest=TestParquetReader -Dhadoop.version=3.4.1

This is disappointing as it means

1. the hadoop release process hasn't been doing the parquet build and test (it's an optional action)
2. this got through our own large scale QE testing.

The good news: this hasn't surfaced in production, presumably because nothing is trying to read into direct buffers -something parquet blocks automatically.
