Gergo Repas commented on YARN-5028:
-----------------------------------
[~yufeigu] Yes, sure - I started out with an empty submission context, but the
recovery failed at certain points (when running on a real cluster). From the
stack traces it was pretty clear which field was missing for the recovery, and
added those to the context until recovery succeeded without any issue - this
covers the first four fields of the quoted section. The last two fields were
needed for all unit tests to pass.
Please let me know if you need the exact stack traces where these fields are
needed, it takes some time to produce those so I'll wait for your reply.

> 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}}.
