> DistributedFileSystem#getFileChecksum of a snapshotted file includes
> non-snapshotted content.
> The reason why this happens is because DistributedFileSystem#getFileChecksum
> simply calculates the checksum of all of the CRCs from the blocks in the
> file. But, in the case of a snapshotted file, we don't want to include data
> in the checksum that was appended to the last block in the file after the
> snapshot was taken.
