Subject [jira] [Created] (HDFS-13037) Support protected path configuration
Date Fri, 19 Jan 2018 03:55:00 GMT
chuanjie.duan created HDFS-13037:

             Summary: Support protected path configuration
                 Key: HDFS-13037
                 URL: https://issues.apache.org/jira/browse/HDFS-13037
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: namenode
            Reporter: chuanjie.duan

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 add a configuration, then user can custom
their own protected path. Just for any accident.

1. add configuration to hdfs-site.xml

2. add a command in dfsadmin for refreshing
