Gergo Repas commented on YARN-5028:
-----------------------------------
[~rohithsharma] [~yufeigu] - A pi job produced 1891 byte long znode with trunk
code, 1866 byte long znode with trunk+YARN-5028.004.patch.
Because of the above results I created YARN-5028.005.patch which keeps only the
ACL information from the AMContainerSpec, this patch produced a 200 byte long
znode for the same pi job.

> 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}}.
