> Currently, HDFS does block corruption tests by directly accessing the files stored on
the storage directories, which assumes {{FsDatasetImpl}} is the dataset implementation. However,
with works like OZone (HDFS-7240) and HDFS-8679, there will be different FsDataset implementations.

> So we need a general way to run whitebox tests like corrupting blocks and crc files.
