Jason Lowe updated YARN-93:
---------------------------
Attachment: YARN-93.patch
Patch to add diagnostics for finished apps.
This adds a new {{RMAppFinishedAttemptEvent}} class which contains the
diagnostics from the finished attempt, but we could also repurpose the existing
{{RMAppFailedAttemptEvent}} class. The name would have to change to clarify
its new role, e.g. RMAppEndedAttemptEvent.
I could see benefits of implementing it either way, so let me know if you
prefer one or the other.
> Diagnostics missing from applications that have finished but failed

>
> If an application finishes in the YARN sense but fails in the app framework
> sense (e.g.: a failed MapReduce job) then diagnostics are missing from the RM
> web page for the application. The RM should be reporting diagnostic messages
> even for successful YARN applications.
