--------------------------------------

             Summary: 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


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.
