ASF GitHub Bot updated SPARK-25689: ----------------------------------- Labels: pull-request-available (was: ) > Move token renewal logic to driver in yarn-client mode > ------------------------------------------------------ > > Key: SPARK-25689 > URL: https://issues.apache.org/jira/browse/SPARK-25689 > Project: Spark > Issue Type: Improvement > Components: Spark Core, YARN > Affects Versions: 2.4.0 > Reporter: Marcelo Masiero Vanzin > Assignee: Marcelo Masiero Vanzin > Priority: Minor > Labels: pull-request-available > Fix For: 3.0.0 > > > Currently, both in yarn-cluster and yarn-client mode, the YARN AM is > responsible for renewing delegation tokens. That differs from other RMs > (Mesos and later k8s when it supports this functionality), and is one of the > roadblocks towards fully sharing the same delegation token-related code. > We should look at keeping the renewal logic within the driver in yarn-client > mode. That would also remove the need to distribute the user's keytab to the > AM when running in that particular mode. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
