This got me quite confused for a while, when I upgraded from 0.16.0 to 0.1.0, but the web GUI was still showing the old version. I guess master.jsp should import oah.hbase.util.VersionInfo rather than oah.hadoop.util.VersionInfo. I checked trunk on SVN and master.jsp still reports the Hadoop version number, not HBase. Actually, it may not be a bad idea to display both hadoop and hbase versions on the webapp, now that they aren't necessarily the same.
