> After add some metrics functions to DFSClient, I found that some unit tests
> relates to metrics are failed. Because MiniDFSCluster are never close open
> FileSystems, DFSClients are alive after MiniDFSCluster shutdown(). The
> metrics of DFSClients in DefaultMetricsSystem are still exist and this make
> other unit tests failed.
