Apache Spark reassigned SPARK-25689: ------------------------------------ Assignee: (was: Apache Spark) > 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: YARN > Affects Versions: 2.4.0 > Reporter: Marcelo Vanzin > Priority: Minor > > 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 (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
