>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: fs/swift
>    Affects Versions: 2.7.1
>            Reporter: Chen He
>
> Current swift driver will encounter authentication issue if swift server has 
> token timeout. It will be good if driver can automatically renew once it 
> expired. We met HTTP 401 error when transferring a 100gb file to swift object 
> store. Since the large file is chunked into 27 files, the server will ask 
> each chunk for token inspection. If server has timeout and 100GB file 
> transferring time is longer than this timeout, token will expire and the file 
> transferring will fail.
