> o.a.h.f.FileSystem has several methods which accepts directly or indirectly a ChecksumOpt
parameter to configure checksum options, but there's no generic way of querying checksum options
used for a given file.
> MD5MD5CRC32FileChecksum used by DFSClient has a getChecksumOpt() but since not just DistributedFileSystem
is accepting a ChecksumOpt argument, but any FileSystem subclass (although only DistributedFileSystem
implements a specific behaviour), I suggest to make getChecksumOpt an abstract method of FileChecksum.
This could be used by tools like DistCp to replicate checksum options for example.
