Gabor Bota commented on HADOOP-16201:
-------------------------------------
That's because there's no such thing as directory in S3. However we have to
handle directories in metadata stores.
For reference:

> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Lokesh Jain
> Assignee: Lokesh Jain
> Priority: Major
>
> S3AFileSystem#innerMkdirs currently does not create parent directories. The
> code checks for the existence of the parent directories and if they do not
> exist, it adds them to metadataStoreDirs list. But this list is not used and
> therefore the parent directories are never created. Only the given directory
> path is created.
