Wangda Tan commented on YARN-3216: ---------------------------------- Thanks for sharing your thoughts, [~sunilg], [~Naganarasimha]. Reconsidered this problem, I prefer to go with option-2, partition should be considered as a sub-cluster, so it should have its own max-am-resource-percentage. I think what we can do is: - Have a per-queue-per-partition "max am percentage" configuration, if it not specific, we assume it inherits queue's configured one. - We guarantee to launch at least one AM container in every partition no matter which is the AM-resource-percentage setting. - If we change node's label, we should update per-queue-per-partition-am-used resource as well. (We have YARN-4082 committed). Sounds like a plan? :) > Max-AM-Resource-Percentage should respect node labels > ----------------------------------------------------- > > Key: YARN-3216 > URL: https://issues.apache.org/jira/browse/YARN-3216 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Wangda Tan > Assignee: Sunil G > Priority: Critical > Attachments: 0001-YARN-3216.patch > > > Currently, max-am-resource-percentage considers default_partition only.
