-----------------------------------

             Summary: NameNode support for protected directories
                 Key: HDFS-8983
                 URL: https://issues.apache.org/jira/browse/HDFS-8983
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 2.7.1
            Reporter: Arpit Agarwal


To protect important system directories from inadvertent deletion (e.g. /Users) 
the NameNode can allow marking directories as _protected_. Such directories 
cannot be deleted unless they are empty.
