You need to set UTF8 as the encoding.
+1 once that's resolved and pending jenkins
> 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.
