Eric Payne commented on YARN-5892: ---------------------------------- Thanks a lot [~sunilg] for your review and comments. {quote} {code} 495 if (activeUsersSet.contains(userName)) { 496 user.setUserResourceLimit(userSpecificUserLimit); 497 } {code} If activeUsersSet has userName, i think user cant be null. Correct? {quote} Correct. A check for null {{user}} could be added, just for safety, but I think it would be redundant. > Capacity Scheduler: Support user-specific minimum user limit percent > -------------------------------------------------------------------- > > Key: YARN-5892 > URL: https://issues.apache.org/jira/browse/YARN-5892 > Project: Hadoop YARN > Issue Type: Improvement > Components: capacityscheduler > Reporter: Eric Payne > Assignee: Eric Payne > Attachments: Active users highlighted.jpg, YARN-5892.001.patch, > YARN-5892.002.patch, YARN-5892.003.patch, YARN-5892.004.patch, > YARN-5892.005.patch, YARN-5892.006.patch, YARN-5892.007.patch, > YARN-5892.008.patch, YARN-5892.009.patch > > > Currently, in the capacity scheduler, the {{minimum-user-limit-percent}} > property is per queue.
