Description

noticed that hbase version always prints out an md5 for source but since we long retired md5 from the releases, it makes sense to replace hbase version information as well. I also noticed that revision doesn't always show, case in point HBase 2.2.0 RC4 vote, revision=Unknown. In my tests, revision only appears if the compiled code was cloned from git and not a release candidate download file. In that sense, release candidates should be checked out rather than downloaded. This Jira only addresses replacement of the md5 sum.
