> Reporter: Yongjun Zhang

> Given a directory owned by user A with permissions 0700 containing an empty
> directory owned by user B, it is not possible to delete user B's directory.
> This is incorrect. Write permission on the containing directory should be all
> that is needed to delete the child directory. Here's a reproduction:
> {code}
> [root@vm01 ~]# hdfs dfs -ls /user/
> Found 4 items
> drwxr-xr-x - userabc users 0 2013-05-03 01:55 /user/userabc
> drwxr-xr-x - hdfs supergroup 0 2013-05-03 00:28 /user/hdfs

> drwxr-xr-x - hdfs supergroup 0 2013-04-14 16:46 /user/hive
> [root@vm01 ~]# hdfs dfs -ls /user/userabc
> Found 8 items
> drwx------ - userabc users 0 2013-05-02 17:00 /user/userabc/.Trash

> [root@vm01 ~]# hdfs dfs -ls /user/userabc/foo/
> [root@vm01 ~]# sudo -u userabc hdfs dfs -rm -r -skipTrash /user/userabc/foo
> rm: Permission denied: user=userabc, access=ALL,
> inode="/user/userabc/foo":hdfs:users:drwxr-xr-x
> {code}
> The super user can delete the directory.
> {code}
> [root@vm01 ~]# sudo -u hdfs hdfs dfs -rm -r -skipTrash /user/userabc/foo
> Deleted /user/userabc/foo
> {code}
> The same is not true for files, however. They have the correct behavior.
