Miklos Szegedi commented on YARN-7715: -------------------------------------- updateContainer only supports execution type updates so far. A vcore increase or decrease does not trigger it. I agree, it should. This Jira was about promotion, that one is about resource change. Would you like to file a JIRA? Do you mean state store in the second case? I think that is legit, however it is also out of the scope of this patch. [~haibochen], [~asuresh], what do you think? Do we need/have the opportunistic flag in state store? > Support NM promotion/demotion of running containers. > ---------------------------------------------------- > > Key: YARN-7715 > URL: https://issues.apache.org/jira/browse/YARN-7715 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Arun Suresh > Assignee: Miklos Szegedi > Priority: Major > Fix For: 3.2.0 > > Attachments: YARN-7715.000.patch, YARN-7715.001.patch, > YARN-7715.002.patch, YARN-7715.003.patch, YARN-7715.004.patch > > > In YARN-6673 and YARN-6674, the cgroups resource handlers update the cgroups > params for the containers, based on opportunistic or guaranteed, in the > *preStart* method. > Now that YARN-5085 is in, Container executionType (as well as the cpu, memory > and any other resources) can be updated after the container has started. This > means we need the ability to change cgroups params after container start. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
