Hi [~dmtucker],

This issue looks interesting. Have you got any updates on this? Do you mind I work on it?

>                 URL: https://issues.apache.org/jira/browse/HDFS-11557
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: hdfs
>    Affects Versions: 2.7.3
>            Reporter: David Tucker
> To reproduce, create a directory without read and/or execute permissions (i.e. 0666,
0333, or 0222), then call delete on it with can_recurse=True. Note that the delete succeeds
even though the client is unable to check for emptiness and, therefore, cannot otherwise know
that any/all children are deletable.
