> HDFS-8983 add  fs.protected.directories to support protected directories on 
> NameNode.  But as I test, when set a parent directory(eg /testA)  to 
> protected directory, the child directory (eg /testA/testB) still can be 
> deleted or renamed. When we protect a directory  mainly for protecting the 
> data under this directory , So I think the child directory should not be 
> delete or renamed if the parent directory is a protected directory.
