https://community.cloudera.com/t5/Support-Questions/How-to-reissue-a-delegated-token-after-max-lifetime-passes/m-p/240822#M202626 <P>This is exactly the way we use spark-submit. A token is valid only for 24 hrs. Yarn renew the token every 24 hrs automatically until it reaches the max lifetime (which is 7 days) then the token cannot get renewed anymore and needs to be reissued. Hence, we are restarting the job every 7 days. Restarting the job every 7 days doesn't seem to be the right approach for a production environment! </P> Thu, 03 Jan 2019 08:52:16 GMT alinazemian 2019-01-03T08:52:16Z
