描述
In case of hardware failure (disk, memory, etc), there might be corrupted bytes. That will result in ArrayIndexOutOfBoundException or/and data garbled.
Currently, jobs reading those Parquet files will fail unless the corrupted files are deleted/moved.
It would be better if Parquet provide an option to skip entire row group (and report how many rows being affected) in case of corrupted bytes.

调研方向
未指定文件、测试或入口点。首先跟踪 Parquet Java 的行组读取以及其对损坏字节的处理;当一种 opt-in 行为可以跳过受影响的行组,并报告有多少行受到影响时,即表示完成。
