----------------------------------------
I believe he's not on the contributor list which is why he can't assign this to
himself.
> WebHDFS CREATE and MKDIRS does not follow same rules as DFS CLI when creating
> files/directories without specifying permissions

> WebHDFS methods for creating file/directories are always creating it with 755
> permissions as default, even ignoring any configured
> *fs.permissions.umask-mode* in the case of directories.
> Dfs CLI, however, applies the configured umask to 777 permission for
> directories, or 666 permission for files.
> Example below shows the different behaviour when creating directory via CLI
> and WebHDFS:
> {noformat}
> 1) Creating a directory under '/test/' as 'test-user'. Configured
> fs.permissions.umask-mode is 000:
> $ sudo -u test-user hdfs dfs -mkdir /test/test-user1
> $ sudo -u test-user hdfs dfs -getfacl /test/test-user1
> # file: /test/test-user1
> # owner: test-user
> # group: supergroup
> user::rwx
> group::rwx
> other::rwx
> 4) Doing the same via WebHDFS does not get the proper ACLs:
> $ curl -i -X PUT
> "http://namenode-host:50070/webhdfs/v1/test/test-user2?user.name=test-user&op=MKDIRS";
>
> $ sudo -u test-user hdfs dfs -getfacl /test/test-user2
> # file: /test/test-user2
> # owner: test-user
> # group: supergroup
> user::rwx
> group::r-x
> other::r-x
> {noformat}
