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

Bắt đầu với TestParquetReader.java, quanh closeAllocator và stack trace của readVectored, sau đó kiểm tra đường đi của ParquetFileReader.readVectored() và việc sử dụng TrackingByteBufferAllocator. Tái hiện bằng mvn -Dtest=TestParquetReader -Dhadoop.version=3.4.1; được xem là hoàn tất khi bài kiểm thử chạy thành công mà không có buffer bị rò rỉ trên Hadoop 3.4.0 hoặc mới hơn.

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.
