Eric Payne created YARN-10009:
---------------------------------
Summary: DRF can treat minimum user limit percent as a max when
custom resource is defined
Key: YARN-10009
URL: https://issues.apache.org/jira/browse/YARN-10009
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Eric Payne
| | 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.
