Ayush Saxena commented on HDFS-15243:
-------------------------------------
You tend to allow read/write but just prevent delete?
prevent deletion of sub-directories or even files under the protected
directories?
Can you elaborate a little more.
In any case, we can't change the existing behavior, may be we can introduce a
new configuration, to make the protected-Directories recursive or something
like that.
Let me know if you would like to work on this, Will assign the Jira to you..

> 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.
