             Summary: Support AM restart in Kerberos secured YARN after the original token in launch context expires
                 Key: SAMZA-929
                 URL: https://issues.apache.org/jira/browse/SAMZA-929
             Project: Samza
          Issue Type: Sub-task
            Reporter: Yi Pan (Data Infrastructure)


In Kerberos secured YARN cluster, an initial token is given in the launch context to RM for a job. When that token expires, RM will not be able to restart failed AM. As for now, we will have to re-submit the job to refresh the token in the launch context.

This ticket is searching for a solution that can refresh the token in the launch context for AM.
