> | | Memory | Vcores | res_1 |
> | Queue1 Totals | 20GB | 100 | 80 |
> | Resources requested by App1 in Queue1 | 8GB (40% of total) | 8 (8% of total) | 80 (100% of total) |
> In the previous use case:
> - Queue1 has a value of 25 for {{miminum-user-limit-percent}}
> - User1 has requested 8 containers with {{<memory:1GB, vcores:8, res_1:10>}} each
> - {{res_1}} will be the dominant resource this case.
> All 8 containers should be assigned by the capacity scheduler, but with min user limit pct set to 25, only 3 containers are assigned.
