Review comment:
It seems related to YARN behavior. YARN will try to renew delegation
token when the job is submitted to YARN. For the customer case, the delegation
token is already obtained when calling `spark-submit`. But YARN is unable to
renew the DT and refuses the job. This config is for such case to avoid YARN to
renew the DT.
