> 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.
