Jeff Evans created SPARK-30256: ---------------------------------- Summary: Allow SparkLauncher to sudo before executing spark-submit Key: SPARK-30256 URL: https://issues.apache.org/jira/browse/SPARK-30256 Project: Spark Issue Type: Improvement Components: Spark Submit Affects Versions: 3.0.0 Reporter: Jeff Evans
It would be useful if {{org.apache.spark.launcher.SparkLauncher}} allowed for a "sudo as user X" option. This way, multi-tenant applications that run Spark jobs could give end users greater security, by ensuring that the files (including, importantly, keytabs) can remain readable only by the end users instead of the UID that runs this multi-tenant application itself. I believe that {{sudo -u <theUser> spark-submit <spark-submit-args}} should work. The builder maintained by {{SparkLauncher}} could simply have a {{setSudoUser}} method. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
