>                 Key: HADOOP-18537
>                 URL: https://issues.apache.org/jira/browse/HADOOP-18537
>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: fs/s3
>            Reporter: TongMingda
>            Priority: Major
>
> I see the code of s3a create(Path f, etc) which does not create target middle 
> directories,
> So whether exist this one case in which I create only one file  "/a/b/c.txt", 
> It can get "b" as a directory by list "/a/", but If we delete this key 
> "/a/b/c.txt",  "a" and "b" directories are all gone disappear.  
> In the end, I want to ask two questions
> 1) Whether HCFS interface create(Path f, etc) need to create target middle 
> directories inside?(sorry did not find doc to say about this)
> 2) If not create target middle directories inside, Is the object storage(s3a) 
> scenario described above plausible?
