-----------------------------------
Assignee: (was: Stefano Baghino)
> Allow per-job Kerberos authentication
> --------------------------------------
>
> Key: FLINK-3699
> URL: https://issues.apache.org/jira/browse/FLINK-3699
> Project: Flink
> Issue Type: Improvement
> Components: JobManager, Scheduler, TaskManager, YARN Client
> Affects Versions: 1.0.0
> Reporter: Stefano Baghino
> Labels: kerberos, security, yarn
>
> Currently, authentication in a secure ("Kerberized") environment is performed
> once as a standalone cluster or a YARN session is started up. This means that
> jobs submitted will all be executed with the privileges of the user that
> started up the cluster. This is reasonable in a lot of situations but
> disallows a fine control over ACLs when Flink is involved.
> Adding a way for each job submission to be independently authenticated would
> allow each job to run with the privileges of a specific user, enabling much
> more granular control over ACLs, in particular in the context of existing
> secure cluster setups.
> So far, a known workaround to this limitation (at least when running on YARN)
> is to run a per-job cluster as a specific user.
