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.
