Steve Loughran created SPARK-13148: -------------------------------------- Summary: support zero-keytab Oozie application launch on a secure cluster Key: SPARK-13148 URL: https://issues.apache.org/jira/browse/SPARK-13148 Project: Spark Issue Type: New Feature Components: YARN Affects Versions: 1.6.0 Environment: YARN cluster with Kerberos enabled, launched from Oozie —where Oozie passes down the delegation tokens Reporter: Steve Loughran
Oozie can launch Spark instances on insecure clusters, and on a secure cluster if Oozie is set up to provide a keytab. What it cannot currently do is launch a Spark application on a YARN cluster without a keytab. In this situation, Oozie collects the delegation tokens it is setup to collect (as a superuser in the cluster), saves them to a file, then points to the file in the `HADOOP_TOKEN_FILE_LOCATION` environment variable. These tokens need to be used to launch the application —rather than try to get some more -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
