[jira] [Updated] (YARN-4945) [Umbrella] Capacity Scheduler
Preemption Within a queue
[ https://issues.apache.org/jira/browse/YARN-4945?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sunil G updated YARN-4945:
--------------------------
Attachment: YARN-2009-wip.v3.patch
Attaching an interim patch which addresses below points:
- Reuse existing TempQueuePerPartition which is stored in PCPP. This avoids some extra logic
- UnsupportedOperationException issue is fixed
- UT tests are passing
Currently {{deductPreemptableResourcesBasedSelectedCandidates}} logic is merged with {{computeIntraQueuePreemptionDemand}}. I think I can refactor same. Also will add the discussed new configuration params in next patch.
