Steve Loughran updated HADOOP-14556:
------------------------------------
Description:
S3A to support delegation tokens where
* an authenticated client can request a token via
{{FileSystem.getDelegationToken()}}
* Amazon's token service is used to request short-lived session secret & id;
these will be saved in the token and marshalled with jobs
* A new authentication provider will look for a token for the current user and
authenticate the user if found
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.
