-----------------------------
Summary: Need to support "dominant" component concept inside YARN service
(was: Need to support pluggable termination policy for native services)
> 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
> 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.
> There're some jobs/services need different policy. For example, if Tensorflow
> master component terminated (regardless of succeed or finished), we need to
> terminate whole training job regardless or other states of other components.
