    Description

      While reviewing patch for YARN-65, I found that many places RMAppImpl#submissionContext sets containerLaunchcontext#setTokensConf has been set to null i.e

      // set the memory free
      app.submissionContext.getAMContainerSpec().setTokensConf(null);
      

      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.
