Description

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.
