> 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.
