> Trying to verify latest release (1.2.1), and I found it a bit inconvenient to parse the
*.mds checksum file. The line wrapping, white space, and the general format of the file does
not lend itself for easy verification.
> I suggest using the standard "coreutils" format for md5sum, sha*sum, etc., instead: <lowercase-hash><space><asterisk(binary-flag)><filename>
> {code}
> # md5

*hbase-1.2.1-src.tar.gz
> {code}
> (comment lines added for humans, but ignored by tools; commented out rmd160, because
not a coreutils supported algorithm; binary flag optional, could use another space instead...
probably only matters for some dos tools)
> This makes it very easy to verify multiple files and hashes using: {{shasum -c file.mds}}
or {{sha1sum -c file.mds}} or {{md5sum -c file.mds}}.
> In addition to the file format change, I suggest these two additional changes:
> 1. Drop rmd160. It's not nearly as popular as the others, and it doesn't lend itself
to easy verification (no coreutils equivalent command like md5sum, sha1sum, etc.)
> 2. Concatenate hashes from all files into a single file. This makes it easier to verify
all downloads at once.
