> RMStateStore stores enough information to recover applications in case of a
> restart. The store also retains this information for completed applications
> to serve their status to REST, WebUI, Java and CLI clients. We don't need all
> the information we store today to serve application status; for instance, we
> don't need the {{ApplicationSubmissionContext}}.
