Eric Payne commented on YARN-5892: ---------------------------------- bq. Yes, we could discuss more about the definition in separate jira. For now, could we avoid taking 0 as a valid configuration. Having 0 as a user weight doesn't hurt anything except the user is never assigned resources. However, I can never think of a use case where <0 would be allowed. I can add a check for <=0, return value of 1.0 for the weight, and log a warning. > 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.
