> library used: org.apache.hadoop:hadoop-openstack:2.6.0
> For long running Swift read operation (e.g., reading a large container), the 
> issued auth token has at most 30 minutes life span from Oracle Storage 
> Service. If the token expired in the middle of the read operation the 
> SwiftRestClient 
> (https://github.com/apache/hadoop/blob/release-2.6.0/hadoop-tools/hadoop-openstack/src/main/java/org/apache/hadoop/fs/swift/http/SwiftRestClient.java#L1701)
>  re-authenticate and acquire a new auth token. However, in the retry request 
> the old, expired token is still used, causing the whole operation to fail.
> Because of this bug any meaningful(i.e., long-running) Swift operation is not 
> possible.
