Hi, We are using a headless keytab to run our long-running spark streaming application. The token is renewed automatically every 1 day until it hits the max life limit. The problem is token is expired after max life (7 days) and we need to restart the job. Is there any way we can re-issue the token and pass it to a job that is already running? It doesn't feel right at all to restart the job every 7 days only due to the token issue.
P.S: We use "--keytab /path/to/the/headless-keytab", "--principal principalNameAsPerTheKeytab" and "--conf spark.hadoop.fs.hdfs.impl.disable.cache=true" as the arguments for spark-submit command. Thanks, Ali
