> Currently, we can use bin/hbase VersionInfo to get jar svn version information, but that is not necessarily the jar of the currently-running process.  HBase.getClusterStatus() contains SVN info for the running primary HMaster process.  We need to add a way to get SVN version information for online RegionServers (more important) & Backup HMasters (not so important).  With the addition of rolling upgrades, we are more likely to get into a situation where part of the RS in our cluster is on a different version.  If we start seeing problems during rolling, it would be nice to know if this might be a versioning problem.
