Summary: S3A to support Delegation Tokens
Key: HADOOP-14556
URL: https://issues.apache.org/jira/browse/HADOOP-14556
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Reporter: Steve Loughran
Assignee: Steve Loughran
S3A to support delegation tokens where
* authenticated client can request a token via
{{FileSystem.getDelegationToken()}}
* STS is used to request short-lived session secret & id; these will be saved
in the token and marshalled with jobs
* new authentication provider to look for a token for the current user.
This will not support renewals; the lifespan of a token will be limited to the
initial duration. Also, as you can't request an STS token from a temporary
session, IAM instances won't be able to issue tokens.
