> In order to support HADOOP-8060, MD5MD5CRC32FileChecksum needs to be extended to carry
the information on the actual checksum type being used. The interoperability between the extended
version and branch-1 should be guaranteed when Filesystem.getFileChecksum() is called over
hftp, webhdfs or httpfs.
