Szilard Nemeth resolved YARN-10908. ----------------------------------- Resolution: Invalid > Investigate: Why AbstractCSQueue#authorizer is constructed for each queue > ------------------------------------------------------------------------- > > Key: YARN-10908 > URL: https://issues.apache.org/jira/browse/YARN-10908 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Szilard Nemeth > Assignee: Szilard Nemeth > Priority: Minor > > AbstractCSQueue#hasAccess checks if a certain user with an ACL has permission > to submit an app to the queue. > Checking the permission itself is performed by calling > ConfiguredYarnAuthorizer#checkPermission. > Interestingly, all queue objects have a reference to a > YarnAuthorizationProvider instance. > What looks weird is how the authorizer is initialized: > https://github.com/apache/hadoop/blob/ac0a4e7f589e7280268013c56339b3b257d332a0/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/scheduler/capacity/AbstractCSQueue.java#L428 > It just calls YarnAuthorizationProvider.getInstance with the Configuration > object as an argument so actually, all queue objects have an instance > constructed with the same configuration, and the getInstance method does not > gather any queue-specific configuration value from the object so this is a > waste of memory. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
