Greg Phillips updated YARN-5280: -------------------------------- Attachment: YARN-5280.003.patch * Removed sandbox modes, now just true/false for enabled/disabled. ** Permissive mode unnecessary since ApplicationMaster containers run within security manager, so any ApplicationMaster needs to be trusted to function. * Refactored yarn configurations into YarnConfiguration * Updated documetation * Updated unit tests > Allow YARN containers to run with Java Security Manager > ------------------------------------------------------- > > Key: YARN-5280 > URL: https://issues.apache.org/jira/browse/YARN-5280 > Project: Hadoop YARN > Issue Type: New Feature > Components: nodemanager, yarn > Affects Versions: 2.6.4 > Reporter: Greg Phillips > Assignee: Greg Phillips > Priority: Minor > Labels: oct16-medium > Attachments: YARN-5280.001.patch, YARN-5280.002.patch, > YARN-5280.003.patch, YARN-5280.patch, YARNContainerSandbox.pdf > > > YARN applications have the ability to perform privileged actions which have > the potential to add instability into the cluster. The Java Security Manager > can be used to prevent users from running privileged actions while still > allowing their core data processing use cases. > Introduce a YARN flag which will allow a Hadoop administrator to enable the > Java Security Manager for user code, while still providing complete > permissions to core Hadoop libraries. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
