Date Fri, 19 Jan 2018 03:57:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-13037?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

chuanjie.duan updated HDFS-13037:
---------------------------------
    Description: 
After Hadoop2.7 root path("/") cannot be deleted for any situration. But like '/tmp','/user','/user/hive/warehouse'
and so on, shouldn't be deleted mostly. So can we let user config  their own custom protected
path. Just for any accident.

1. add configuration to hdfs-site.xml

2. add a command in dfsadmin for refreshing
