Sunil G commented on YARN-3733: ------------------------------- Thank you [~rohithsharma] for the detailed information and patch. 1. Could we add a test case where only memory or vcores are more in TestCapacityScheduler. {code} Resource amResource2 = Resource.newInstance(amResourceLimit.getMemory() + 1, amResourceLimit.getVirtualCores()); {code} 2. In TestCapacityScheduler#verifyAMLimitForLeafQueue, while submitting second app, you could change the app name to "app-2". > DominantRC#compare() does not work as expected if cluster resource is empty > --------------------------------------------------------------------------- > > Key: YARN-3733 > URL: https://issues.apache.org/jira/browse/YARN-3733 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 2.7.0 > Environment: Suse 11 Sp3 , 2 NM , 2 RM > one NM - 3 GB 6 v core > Reporter: Bibin A Chundatt > Assignee: Rohith > Priority: Blocker > Attachments: 0001-YARN-3733.patch, 0002-YARN-3733.patch, > YARN-3733.patch > > > Steps to reproduce > ================= > 1. Install HA with 2 RM 2 NM (3072 MB * 2 total cluster) > 2. Configure map and reduce size to 512 MB after changing scheduler minimum > size to 512 MB > 3. Configure capacity scheduler and AM limit to .5 > (DominantResourceCalculator is configured) > 4. Submit 30 concurrent task > 5. Switch RM > Actual > ===== > For 12 Jobs AM gets allocated and all 12 starts running > No other Yarn child is initiated , *all 12 Jobs in Running state for ever* > Expected > ======= > Only 6 should be running at a time since max AM allocated is .5 (3072 MB) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
