Subject [jira] Created: (HBASE-2932) Allow Per-Process SVN Version Information
Date Sat, 21 Aug 2010 00:43:17 GMT
Allow Per-Process SVN Version Information

                 Key: HBASE-2932
                 URL: https://issues.apache.org/jira/browse/HBASE-2932
             Project: HBase
          Issue Type: Improvement
          Components: ipc, master, regionserver, scripts
            Reporter: Nicolas Spiegelberg
            Assignee: Nicolas Spiegelberg
            Priority: Minor

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.
