> In hadoop-metrics.properties, GangliaContext is optional metrics context, I think we will use ganglia to monitor hbase cluster generally.
> However, I find a serious problem:
> RegionServerDynamicMetrics will generate lots of rrd file because we would move region or create/delete table.
> Especially if table is created everyday in some applications, there are much more and more rrd files in Gmetad Server. It will make Gmetad Server corrupted.
> IMO, MetricsContext should be different between RegionServerMetrics and RegionServerDynamicMetrics
