Ravi Prakash commented on MAPREDUCE-3688:
-----------------------------------------

Hi Sandy! Did you think about this? Otherwise I'll be happy to take this back and work on it in this week.

>From my testing on trunk, I notice that even for the case where the AM goes over container limits (which I trigger with -Dyarn.app.mapreduce.am.resource.mb=512 -Dyarn.app.mapreduce.am.command-opts="-Xmx3500m" on a sleep job), sometimes the error is propagated back and sometimes its not. Can you please corroborate this? When State == FinalState == FAILED, the error is propagated back. However about half the times, State == FINISHED and FinalState == KILLED, in which case there is no message anywhere to help me. Not in the diagnostics, and there are no logs.

> We need better error messages in the UI if the AM gets killed or throws an Exception.
> If the following error gets thrown: 
> java.lang.NumberFormatException: For input string: "9223372036854775807l" // last char is an L
> then the UI should say this exception.  Instead I get the following:
> Application application_1326504761991_0018 failed 1 times due to AM Container for appattempt_1326504761991_0018_000001
> exited with exitCode: 1 due to: Exception from container-launch: org.apache.hadoop.util.Shell$ExitCodeException
