> The yarn logs command is among the most common ways to troubleshoot yarn app
> failures, especially by an admin.
> Currently if you run the command as a user different from the job owner, the
> command will fail with a subtle message that it could not find the app under
> the running user's name. This can be confusing especially to new admins.
> We can figure out the job owner from the app report returned by the RM or the
> AHS, or, by looking for the app directory using a glob pattern, so in most
> cases this error can be avoided.
> Question - are there scenarios where users will still need to specify the
> -appOwner option?
