> Key: YARN-6982
> URL: https://issues.apache.org/jira/browse/YARN-6982
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Rohith Sharma K S
> Assignee: Manikandan R
> Fix For: 2.9.0, 3.0.0-beta1
>
> Attachments: YARN-6982.001.patch
>
>
> While reviewing patch for YARN-65, I found that many places
> RMAppImpl#submissionContext sets containerLaunchcontext#setTokensConf has
> been set to null i.e
> {code}
> // set the memory free
> app.submissionContext.getAMContainerSpec().setTokensConf(null);
> {code}
> This appears be a issue if application is updated may be because queue move
> or lifetime or priority, then submission context will be restored again into
> state store. Consider after app update, if RM is restarted then submission
> context will have null tokenConf. This could be a potential issue.
