Suma Shivaprasad commented on YARN-8489: ---------------------------------------- [~yuan_zac] Thanks for your interest in this effort. Pls go ahead > Need to support "dominant" component concept inside YARN service > ---------------------------------------------------------------- > > Key: YARN-8489 > URL: https://issues.apache.org/jira/browse/YARN-8489 > Project: Hadoop YARN > Issue Type: Task > Components: yarn-native-services > Reporter: Wangda Tan > Assignee: Suma Shivaprasad > Priority: Major > > Existing YARN service support termination policy for different restart > policies. For example ALWAYS means service will not be terminated. And NEVER > means if all component terminated, service will be terminated. > The name "dominant" might not be most appropriate , we can figure out better > names. But in simple, it means, a dominant component which final state will > determine job's final state regardless of other components. > Use cases: > 1) Tensorflow job has master/worker/services/tensorboard. Once master goes to > final state, no matter if it is succeeded or failed, we should terminate > ps/tensorboard/workers. And the mark the job to succeeded/failed. > 2) Not sure if it is a real-world use case: A service which has multiple > component, some component is not restartable. For such services, if a > component is failed, we should mark the whole service to failed. -- 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
