Kuhu Shukla commented on TEZ-3345:
----------------------------------
[~Sreenath] Thanks a lot.
bq. - Wouldn't the diagnostic message from RM fits better in app details?
If I understand the question correctly, showing the diagnostics on
{{tez-app/application_123_456}} details page would also work, although I am not
sure if we have a diagnostics section in the Application Details section.
> Diagnostics for a failed AM may not show up on the DAG UI page.

> Issue Type: Improvement
> Components: UI

>
> In a scenario where AM fails on all its attempts, the DAG page does not show
> the Diagnostics message on the Tez UI "Diagnostics" section. The messageis
> available on the AHS and could be pulled into the DAG page just like we do
> for failed vertices.
> I ran a simple Tez example job that was given way too less memory causing the
> AM to fail:
> {code}
> hadoop jar /home/gs/tez/current/tez-examples-0.7.1.x.x.jar orderedwordcount
> -Dtez.am.resource.memory.mb=16 -Dtez.am.launch.cmd-opts="-Xmx13m
> -Djava.net.preferIPv4Stack=true -XX:+UseNUMA -XX:+PrintGCDetails
> -XX:+PrintGCDateStamps -Xloggc:<LOG_DIR>/gc.log"/books /output
> {code}
