Steve Loughran updated HADOOP-14556:
------------------------------------
Status: Patch Available (was: Open)
HADOOP-14556 patch 014
* instrumentation to track getDelegationToken() invocation count (new
CommonStatisticNames field), and of tokens issued
* which are probed for in one of the tests
* DelegatedMR job cleaned up, now as much as I can see easily done.
* There's an origin string on token IDs to make it easier to debug; usually:
(hostname, time);
* when propagating session secrets this is noted in origin
* and for role tokens, the role ARN.
* checkstyle and minor cleanups
*This stuff is ready to play with —can anyone have a go?*

> 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.
