[jira] [Updated] (HDFS-5356) MiniDFSCluster shoud close all open FileSystems when shutdown()

     [ https://issues.apache.org/jira/browse/HDFS-5356?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

haosdent updated HDFS-5356:
---------------------------

    Description: 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.
