Prabhu Joseph commented on YARN-10364: -------------------------------------- Thanks [~BilwaST] for the patch. Have a comment in below section 1. AbstractCSQueue#validateAbsoluteVsPercentageCapacityConfig will always succeed as it compares localType copied from this.capacityConfigType with the same this.capacityConfigType. It has to compare the type (this.capacityConfigType) of previous node label with the new one derived using minResource of next node label. Like below. {code} private void validateAbsoluteVsPercentageCapacityConfig( String queuePath, String label) { CapacityConfigType localType = checkConfigTypeIsAbsoluteResource(queuePath, label) ? CapacityConfigType.ABSOLUTE_RESOURCE : CapacityConfigType.PERCENTAGE; if (!queuePath.equals("root") && !this.capacityConfigType.equals(localType)) { throw new IllegalArgumentException("Queue '" + getQueuePath() + "' should use either percentage based capacity" + " configuration or absolute resource."); } } {code} > Absolute Resource [memory=0] is considered as Percentage config type > -------------------------------------------------------------------- > > Key: YARN-10364 > URL: https://issues.apache.org/jira/browse/YARN-10364 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 3.4.0 > Reporter: Prabhu Joseph > Assignee: Bilwa S T > Priority: Major > Attachments: YARN-10364.001.patch, YARN-10364.002.patch > > > Absolute Resource [memory=0] is considered as Percentage config type.
