_{**Note**: *This issue was originally created as [PARQUET-1248](https://issues.apache.org/jira/browse/PARQUET-1248). Please see the [migration documentation](https://issues.apache.org/jira/browse/PARQUET-2502) for further details.*}

Bắt đầu với VectorizedColumnReader.java tại readIntBatch, sử dụng stack trace được cung cấp để hiểu đường dẫn Parquet reader đang bị lỗi. Sau đó đọc tài liệu migration PARQUET-2502 được tham chiếu và xác định liệu tài liệu đó có thay thế báo cáo này hay không; issue hoàn tất khi trạng thái của nó và mọi resolution áp dụng được ghi lại trong đó.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
