Eric Payne updated YARN-1115: ----------------------------- Affects Version/s: (was: 0.23.9) (was: 2.1.0-beta) 2.8.5 > Provide optional means for a scheduler to check real user ACLs > -------------------------------------------------------------- > > Key: YARN-1115 > URL: https://issues.apache.org/jira/browse/YARN-1115 > Project: Hadoop YARN > Issue Type: Improvement > Components: capacity scheduler, scheduler > Affects Versions: 2.8.5 > Reporter: Eric Payne > Priority: Major > > In the framework for secure implementation using UserGroupInformation.doAs > (http://hadoop.apache.org/docs/stable/Secure_Impersonation.html), a trusted > superuser can submit jobs on behalf of another user in a secure way. In this > framework, the superuser is referred to as the real user and the proxied user > is referred to as the effective user. > Currently when a job is submitted as an effective user, the ACLs for the > effective user are checked against the queue on which the job is to be run. > Depending on an optional configuration, the scheduler should also check the > ACLs of the real user if the configuration to do so is set. > For example, suppose my superuser name is super, and super is configured to > securely proxy as joe. Also suppose there is a Hadoop queue named ops which > only allows ACLs for super, not for joe. > When super proxies to joe in order to submit a job to the ops queue, it will > fail because joe, as the effective user, does not have ACLs on the ops queue. > In many cases this is what you want, in order to protect queues that joe > should not be using. > However, there are times when super may need to proxy to many users, and the > client running as super just wants to use the ops queue because the ops queue > is already dedicated to the client's purpose, and, to keep the ops queue > dedicated to that purpose, super doesn't want to open up ACLs to joe in > general on the ops queue. Without this functionality, in this case, the > client running as super needs to figure out which queue each user has ACLs > opened up for, and then coordinate with other tasks using those queues. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
