 To have HBase emit metrics, edit `$HBASE_HOME/conf/hadoop-metrics.properties` and enable metric 'contexts' per plugin.  As of this writing, hadoop supports *file* and *ganglia* plugins. Yes, the hbase metrics files is named hadoop-metrics rather than _hbase-metrics_ because currently at least the hadoop metrics system has the properties filename hardcoded. Per metrics _context_, comment out the NullContext and enable one or more plugins instead.
