If the job lasts longer than a given period of time, then Yarn renews the delegation token (or more precisely, extends its lifetime), therefore allowing the tasks to continue using the delegation token. This is based on the assumption that the delegation token itself is static and doesn't change (only its lifetime can be extended on the target resource's server).
