Thomas Weise commented on YARN-208:
-----------------------------------
In case of State=FAILED, FinalState=FAILED, the override is something like:
{{Application application_1352326804484_0004 failed 1 times due to AM Container
for appattempt_1352326804484_0004_000001 exited with exitCode: 1 due to:
.Failing this attempt.. Failing the application.}}
That is with non zero AM exit code, no trace of the original message.
For FINISHED/SUCCEEDED and FINISHED/FAILED it is blank.
Under either scenario info set by the AM should not be lost.
> Yarn overrides diagnostic message set by AM
