Lei (Eddy) Xu updated HDFS-9188:
--------------------------------
    Attachment: HDFS-9188.000.patch

The patch:
* Provides a Dataset-special TestUtils interface. 
* Provides a {{ReplicaToCorrupt}} interface to abstract out the block implementation (e.g., using File).

> Make block corruption related tests FsDataset-agnostic.

> 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.
